GC-WIFI7 - 5800Mbps Tri-Band Wi-Fi 7 PCIe Card | GIGABYTE
GIGABYTE GC-WIFI7 is a tri-band Wi-Fi 7 PCIe expansion card supporting wireless connections up to 5800Mbps, bandwidth up to 320MHz across 2.4GHz, 5GHz, and 6GHz, and Bluetooth 5.3 in a PCIe x1 low-profile form factor. It is intended for desktop PCs that need a compact, high-throughput wireless upgrade. A Wi-Fi 7 PCIe adapter is a wireless network interface card that adds Wi-Fi and Bluetooth connectivity to a desktop through the PCI Express bus. Unlike a USB dongle, this card uses PCIe x1, reducing dependence on a USB port while supporting modern desktop systems. Its tri-band architecture gives the adapter access to 2.4GHz, 5GHz, and 6GHz networks. The GC-WIFI7 supports up to 320MHz channel bandwidth, Multi-Link Operation (MLO), Multiple RU (MRU), OFDMA efficiency, and 4K-QAM. These features improve link efficiency, interference handling, and multi-link operation. The manufacturer states a maximum wireless speed of 5800Mbps, although actual throughput depends on the router, distance, interference, channel width, and client configuration. Bluetooth 5.3 is also provided for compatible peripherals. The card is based on a PCIe x1 interface and is identified in distributor listings as a low-profile expansion card. Its integrated wireless module and external ultra-high-gain antenna arrangement are intended for desktop use where a PCIe slot and antenna placement are available. It is suitable for gaming PCs, workstation PCs, home systems, and other compatible desktop builds. When selecting an installation location, confirm the case has an available PCIe slot, compatible rear opening, and space for the card and antenna. Drivers and operating-system support should be checked with the manufacturer or system vendor before installation. The 6GHz band requires a compatible access point and suitable regional availability. A practical design consideration is that the advertised 5800Mbps figure is a maximum theoretical connection rate, not guaranteed application throughput. A wired network may still provide lower latency for large transfers. For best results, position the antenna away from metal chassis components and verify router support for 320MHz channels, MLO, and 4K-QAM. This page consolidates verified GIGABYTE product-page and distributor information, including the 5800Mbps maximum, tri-band operation, 320MHz bandwidth, PCIe x1 interface, Bluetooth 5.3, MLO, MRU, and 4K-QAM. It also distinguishes verified specifications from unavailable detailed dimensions, pinout, pricing tiers, and regulatory data.
GP2S+ - 2-Way MMIC Power Splitter 800-2100 MHz | Mini-Circuits
The Mini-Circuits GP2S+ is a 2-way MMIC DC-pass power splitter/combiner covering 800 MHz to 2.1 GHz in a 12-VQFN exposed-pad surface-mount package. Key specifications include a minimum isolation of 17 dB, typical input VSWR of 1.2, and maximum amplitude imbalance of 4 degrees (phase). The device presents a 50-ohm nominal impedance on all ports and is designed for use as both a power splitter and a power combiner in cellular, PCS, DCS, and 3G/4G infrastructure. A power splitter/combiner is a passive RF component that divides an input signal into two equal-amplitude, equal-phase outputs (splitter mode) or combines two coherent signals into a single output (combiner mode). The GP2S+ sits in the hierarchy of RF passives -> power dividers/splitters -> MMIC-based splitters -> DC-pass splitters. The DC-pass capability allows DC bias to flow through the input port to both output ports, simplifying active antenna or amplifier bias-tee designs by eliminating external inductors. Key features include a wideband 800-2100 MHz operating range suitable for all major cellular bands (GSM, CDMA, WCDMA, LTE), a low typical insertion loss, and excellent amplitude/phase balance across the full band. The MMIC die is mounted in a Mini-Circuits-style exposed-pad QFN package that provides a low thermal path and a small PCB footprint. As an RoHS-compliant surface-mount device, it is compatible with modern reflow assembly processes. The GP2S+ is built on a GaAs MMIC process internally matched to 50 ohms, eliminating the need for external matching components. The internal resistors absorb the inherently lost third port of a Wilkinson-style divider, providing high isolation between output ports without external components. The exposed-pad package design ensures stable ground reference and adequate heat dissipation. Typical applications include in-building wireless (DAS) repeaters, cellular base-station signal distribution, RFID reader antenna networks, satellite upconverter local-oscillator distribution, and test-and-measurement signal splitting. The 50-ohm, 2-way topology makes it a natural fit for any application that needs to feed two antennas or two receiver paths from a single source. When designing with this part, note the 12-VQFN footprint requires careful PCB layout with continuous ground under the exposed pad for thermal and RF performance. Bypass any DC feed with a suitable RF choke and DC-blocking capacitor combination as needed for the specific bias-tee topology. This page synthesizes distributor pricing, drop-in MMIC splitter alternatives in the same 12-VQFN footprint, and practical PCB design notes that go beyond the manufacturer datasheet.
GP2S1+ - 2-Way MMIC Power Splitter/Combiner, 500-2500 MHz | Mini-Circuits
The Mini-Circuits GP2S1+ is a 2-way 0° MMIC surface-mount power splitter/combiner covering 500 MHz to 2500 MHz with 50Ω impedance, housed in a 12-pin VQFN (DQ1225) exposed-pad case measuring 3x3 mm. It delivers 9 dB minimum isolation, 1.3 maximum VSWR, and 5° maximum imbalance, and supports DC pass between input and outputs for biasing downstream active circuitry. A power splitter/combiner is a passive RF component that divides an input signal into two equal-amplitude, equal-phase outputs (splitter mode) or, conversely, combines two coherent inputs into a single output (combiner mode). Within the RF component taxonomy, GP2S1+ sits under the Wilkinson family of splitters, implemented here in MMIC form for repeatable, surface-mount manufacturing, sitting inside the broader hierarchy of passive RF components -> signal conditioning -> splitter/combiner. Key features include a wide 500 MHz to 2.5 GHz bandwidth covering major cellular (LTE/5G sub-6 GHz mid-bands), ISM, and Wi-Fi 2.4 GHz bands; 1.8 dB typical insertion loss; excellent amplitude and phase balance; DC pass on all ports; and a low-profile 3x3 mm case. Internal dissipation and input power handling are specified for safe operation as both splitter and combiner. The device uses a resistive-divider/lumped-element MMIC topology rather than a traditional microstrip Wilkinson, which yields its compact DQ1225 case, repeatable S-parameters across production lots, and easy integration into standard SMT reflow lines. The exposed pad provides the necessary thermal path and low-inductance ground for the upper GHz region. Typical applications include in-building DAS (distributed antenna systems) for cellular/LTE, MIMO reference signal distribution, Wi-Fi 2.4 GHz access-point signal chains, test-and-measurement setups needing a wideband splitter, and software-defined radio front-ends. Anywhere a balanced 1-to-2 fan-out is needed between 500 MHz and 2.5 GHz, GP2S1+ is a strong fit. When designing with this part, observe the absolute maximum input power ratings in the datasheet, keep the DC pass current below the limit when biasing downstream LNAs or filters, and provide a continuous ground plane tied to the exposed pad to preserve VSWR and isolation performance. This page combines verified distributor pricing, drop-in pin-compatible alternatives, and practical design notes that go beyond the manufacturer datasheet to help RF engineers select and place GP2S1+ with confidence.
GP2S1A+ - 2-Way MMIC 0.5-2.5 GHz Splitter/Combiner | Mini-Circuits
The Mini-Circuits GP2S1A+ is a 50Ω GaAs MMIC 2-way power splitter/combiner operating from 500 MHz to 2500 MHz with DC pass capability, housed in a 12-lead VQFN exposed-pad (Case DQ1264) surface-mount package. It delivers typical insertion loss of 1.0 dB, 22 dB port-to-port isolation, 0.02 dB amplitude unbalance, and 0.4 deg phase unbalance over its specified band, while handling up to 10 W of input power (with DC pass current up to 370 mA) when used as a combiner. A power splitter is a passive RF network that equally divides an input signal into two output paths (or, used reciprocally, combines two signals into one) while maintaining a 50Ω match at every port. Splitters and combiners are foundational building blocks in RF and microwave systems - they sit inside every phased-array antenna feed network, every dual-path receiver, every in-building DAS (distributed antenna system), and every test-and-measurement setup that needs to monitor a live signal without interrupting it. Mini-Circuits' MMIC (Monolithic Microwave IC) implementation integrates the splitter function on a single GaAs die, replacing bulky discrete Wilkinson designs with a tiny, repeatable, surface-mount part that drops straight onto an SMT line. Key features of the GP2S1A+ include a wide 500-2500 MHz bandwidth covering all major cellular (LTE/5G sub-6 GHz mid-band), Wi-Fi (2.4 GHz), ISM, and GNSS feed-network use cases; excellent amplitude balance (typical 0.02 dB, max 0.4 dB on the full band) and phase balance (typical 0.4 deg, max 4 deg) that preserve signal integrity when the two outputs feed matched-path circuitry; high isolation (17 dB minimum, 22 dB typical) that prevents the split outputs from coupling back into each other; and excellent return loss (22 dB typical) that keeps the splitter essentially invisible in a 50Ω system. The device also passes DC through the center conductor, allowing remote powering of downstream LNAs, filters, or antennas without extra bias tees. The GP2S1A+ uses a GaAs MMIC die (Mini-Circuits die reference DQ1264) wire-bonded into a 12-pin VQFN package. The exposed bottom pad is the RF/DC ground reference and must be soldered to the PCB ground plane with multiple thermal vias for repeatable RF performance, low thermal resistance, and minimum parasitic inductance. DC-pass capability is implemented with on-chip inductors and a center-tap bias path that accepts the bias feed from any output port and routes it to the other output ports - this allows the same part to be used as either a splitter or a combiner with no topology change. Typical applications for the GP2S1A+ include LTE/5G small-cell and femtocell feeder networks, 2.4 GHz Wi-Fi (802.11b/g/n/ax) MIMO feed networks, in-building DAS signal distribution, GNSS (GPS/BeiDou/Galileo/GLONASS) antenna distribution for test and measurement, general-purpose RF signal monitoring/probing in lab instrumentation, and any 50Ω system that needs an ultra-compact, surface-mountable 2-way split. When designing with the GP2S1A+, pay close attention to PCB layout: route the RF traces as 50Ω controlled-impedance lines, stitch the ground paddle with multiple vias, and keep the DC-pass bias trace away from sensitive RF nodes to preserve isolation. Distributor pricing is around $4-6 per unit in small quantities (DigiKey / Mouser) as of 2026-10-13. This page synthesizes distributor pricing and stock data, surface-mount footprint notes, drop-in same-package alternatives, and practical RF layout guidance - content that goes beyond the manufacturer datasheet to speed up your design-in decision.
GP2SA+ - 2-Way MMIC Power Splitter 800-2100 MHz | Mini-Circuits
The Mini-Circuits GP2SA+ is a 50 ohm GaAs MMIC 2-way power splitter/combiner operating from 800 MHz to 2100 MHz in a 12-VQFN exposed-pad surface-mount package. It delivers typical 1.0 dB insertion loss, 22 dB isolation, 0.02 dB amplitude unbalance, and 0.4 degree phase unbalance, with a maximum input power rating of 10 W and DC pass-through capability up to 370 mA. The exposed-pad DQ1225 package style provides a low thermal-resistance path suitable for high-density cellular base-station and small-cell PCB layouts. An RF power splitter (also called a power divider or hybrid combiner) is a passive RF component that splits an input signal into two or more equal-amplitude, equal-phase output signals (acting as a splitter), or conversely combines multiple input signals into a single output (acting as a combiner). In the RF signal chain hierarchy, the splitter sits between the transceiver/driver stage and the antenna or feed network; it belongs to the broader category of RF passive components alongside couplers, attenuators, and filters. The 2-way Wilkinson-style topology used in the GP2SA+ provides matched 50 ohm ports on every node and intrinsic isolation between output ports, making it ideal for cellular BTS, repeater, and distributed-antenna-system front-ends. Key features include wide 800 to 2100 MHz operating bandwidth covering all major cellular sub-2.6 GHz bands, excellent amplitude unbalance of typically 0.02 dB (max 3 dB per data), and 20 dB minimum isolation with 26 dB typical return loss. The DC pass path (up to 370 mA) allows the splitter to feed DC bias to a downstream LNA or antenna-tuner without an external bias-T, simplifying PCB routing and bill of materials. GaAs MMIC construction provides repeatable RF performance from unit to unit across the full operating temperature range. The GP2SA+ utilizes Mini-Circuits' GaAs MMIC process technology with on-chip thin-film resistors and a printed Wilkinson divider structure. Internal compensation networks and on-wafer laser-trimmed resistors achieve the tight amplitude and phase unbalance numbers without external tuning. The MMIC die is mounted in a 12-VQFN exposed-pad (DQ1225) package that minimizes bond-wire inductance and provides a low thermal resistance path to the host PCB ground plane. Typical applications include GSM/CDMA/LTE/UMTS base-station transmit/receive signal splitting, in-building DAS (distributed antenna system) feeders, RFID reader signal distribution, and general-purpose 800 to 2100 MHz test-and-measurement signal routing. The wide bandwidth also suits cellular repeater, small-cell, and picocell radio head networks. The DC pass-through feature lets designers bias remote LNAs through the same RF line, eliminating separate bias networks. When designing with this splitter, ensure the host PCB ground plane connects directly to the exposed pad with multiple thermal vias underneath to maintain low thermal resistance and stable RF grounding. The 50 ohm microstrip or coplanar-wave launch should be designed for the package land pattern given in the datasheet; even small impedance mismatches at the launch degrade the 26 dB return-loss number. When using the DC pass path, insert a suitable RF choke or bias network to prevent RF leakage into the DC supply rail. This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and practical PCB/thermal design notes not consolidated in the Mini-Circuits datasheet alone, giving RF engineers a single source for sourcing and second-source decisions.
GP2Y+ - 2-Way MMIC Power Splitter 1.6-3.3 GHz | Mini-Circuits
The Mini-Circuits GP2Y+ is a 2-way MMIC surface-mount power splitter/combiner covering 1600 MHz to 3300 MHz with 50 ohm impedance, packaged in a 12-VQFN exposed-pad case style DQ1225. Key specs include 1.5 dB typical insertion loss, 17 dB minimum isolation, 1.2:1 typical VSWR, and 4 degree maximum amplitude/phase imbalance. The GP2Y+ is RoHS compliant and operates from -40C to +85C. As a passive MMIC device it requires no external DC bias, simplifying PCB integration. A power splitter/combiner is a passive RF component that divides an input signal into two equal-amplitude outputs (splitter mode) or combines two inputs into a single output (combiner mode). It belongs to the broader category of RF power dividers within signal conditioning components, used in wireless infrastructure, test instrumentation, and phased-array systems. The 2-way topology (one input, two outputs) makes it the most common building block in distribution networks where signal coherence and amplitude balance matter. The GP2Y+ uses Mini-Circuits' proprietary GaAs MMIC process with on-chip resistors for the resistive-divider network, which provides inherently broadband behavior across the 1600-3300 MHz band. The exposed-pad 12-VQFN package (DQ1225) yields a low thermal-resistance path and a compact 3x3 mm footprint suitable for high-density PCB designs. Internal dissipation handling and wideband phase tracking support multi-section use cases such as corporate-feed networks in antenna arrays. Typical applications include LTE/4G and 5G sub-6 GHz infrastructure, in-building DAS (distributed antenna systems), Wi-Fi 2.4 GHz band signal sampling, RFID reader splitting networks, and RF test equipment where repeatable signal division with low loss is required. Its small size and zero-bias operation make it especially attractive for compact module designs. When designing with the GP2Y+, follow the recommended PCB layout (PL-282) on Rogers RO4350B dielectric with continuous bottom-side ground. Maintain 50 ohm trace impedance from input to the splitter junction and from each output port; insufficient trace width degrades VSWR and worsens amplitude balance. Avoid routing DC or digital signals near the RF traces to prevent coupling.
GP2Y1+ - 2-Way MMIC Splitter 1550-4400 MHz | Mini-Circuits
The Mini-Circuits GP2Y1+ is a 2-way MMIC surface-mount power splitter/combiner covering 1550 MHz to 4400 MHz in a 50 ohm environment, housed in a 12-pin DQ1225 case style with exposed pad. It delivers 12 dB minimum isolation, 1.4 typical VSWR, and 6 degree maximum amplitude/phase imbalance across the full band, making it well suited for sub-6 GHz wireless infrastructure. The MMIC die inside is qualified for repeatable performance, and the RoHS-compliant DQ1225 land pattern enables drop-in assembly on standard reflow profiles. An MMIC power splitter is a passive RF component that divides an input signal into two equal-amplitude, equal-phase outputs (splitter mode) or conversely combines two signals into a common port (combiner mode) with high isolation between output ports. Splitters/combiners sit inside the RF front-end hierarchy between the transceiver and the antenna network, where they enable functions such as diversity reception, balanced power amplifier combining, and LO distribution. MMIC realizations use a semiconductor process to integrate resistive or transformer-based networks on a single die, yielding smaller size, broader bandwidth, and tighter unit-to-unit consistency than traditional discrete resistive or Wilkinson designs. Key features include 1.55 GHz to 4.4 GHz operating bandwidth, 1.9 dB insertion loss over the band, 12 dB minimum port-to-port isolation, 1.4 typical VSWR at each port, 6 degree amplitude/phase imbalance maximum, and a robust operating temperature range of -40C to +85C. The DQ1225 case is a 3 mm x 3 mm x 0.9 mm surface-mount land grid compatible with standard pick-and-place and lead-free reflow. Architecturally, the GP2Y1+ uses a GaAs MMIC die with on-waide balun and resistor networks that absorb mismatched power and deliver stable amplitude and phase balance over the 1.55 to 4.4 GHz band. The exposed bottom pad provides a low-inductance RF ground and a thermal path for the die, which improves power handling consistency between units. Typical applications include 4G/LTE and 5G NR sub-6 GHz infrastructure, Wi-Fi 6/6E MIMO radios, point-to-point and small-cell backhaul, GPS/GNSS signal distribution, and test-and-measurement setups where a compact, broadband 2-way resistive/transformer split is required. Designers can use it as a power combiner for balanced PA architectures or as an LO splitter for multi-channel transceivers. When laying out the PCB, keep all three RF traces (J1, J2, J3) length-matched and symmetrically routed away from the part with a continuous ground reference. Place DC-blocking and matching components close to the part and avoid routing high-speed digital lines under the exposed pad to preserve isolation. This page synthesizes distributor pricing, package mechanical drawings, and a drop-in alternatives list with practical design notes that complement the manufacturer datasheet.
GP2Y1A+ - 50Ω GaAs MMIC 2-Way Splitter/Combiner 1550-4400 MHz | Mini-Circuits
The Mini-Circuits GP2Y1A+ is a 50Ω GaAs MMIC 2-way power splitter and combiner operating from 1550 to 4400 MHz with typical insertion loss of 1.1 dB, 22 dB isolation, 0.03 dB amplitude unbalance, and 0.6° phase unbalance, housed in a low-profile surface-mount plastic package. The device handles up to 10 W maximum input power as a splitter and supports bi-directional operation, allowing the same footprint to be used for signal division and signal combining in the field. A power divider (also called a power splitter or combiner) is a passive RF component that splits an input signal into two equal-amplitude, equal-phase outputs, or conversely combines two inputs into a common output while maintaining 50Ω impedance at every port. These components sit at the heart of RF front-end signal chains, where they feed multi-antenna MIMO transceivers, divide local-oscillator (LO) signals among mixers, and combine power amplifier outputs in phased-array and Doherty architectures. Within the broader taxonomy, GP2Y1A+ belongs to passive RF components → RF signal-conditioning passives → RF power dividers/splitters → MMIC splitters → surface-mount MMIC splitters. Key features include a wide bandwidth spanning 1550 to 4400 MHz (covering all cellular mid-band from DCS through C-band), low insertion loss of 1.1 dB (typical) that minimizes signal attenuation, tight amplitude balance of 0.03 dB ensuring equal power division between output ports, and 0.6° phase balance for coherent combining. The GaAs MMIC construction delivers monolithic repeatability versus traditional LTCC or microstrip resistive splitters, while the 50Ω matched design eliminates external matching components. The GP2Y1A+ uses a Mini-Circuits GaAs MMIC die inside a small SMT plastic package compatible with standard reflow profiles. Its broadband behaviour means a single part can replace multiple discrete resistive or reactive splitters in multiband radios, reducing BOM count and simplifying the bill of materials. The 22 dB port-to-port isolation prevents LO leakage between mixer ports in transmit and receive chains. Typical applications include LO distribution in cellular base-station transceivers, 2.4 GHz and 3.5 GHz Wi-Fi MIMO front ends, 5G mid-band small-cell radios, GPS distribution amplifiers, and general test-and-measurement signal splitting. The wide 1550-4400 MHz range makes it a near-universal splitter for sub-6 GHz wireless infrastructure. Key design consideration: pair the GP2Y1A+ with 50Ω microstrip or coplanar-waveguide traces and follow Mini-Circuits' EVB land pattern to maintain return-loss performance above 15 dB. When using as a combiner, ensure outputs are in-phase (differential path-length matched to within 0.6° at the highest frequency of operation) to avoid destructive cancellation.

GP2YA+ - 2-Way MMIC Power Splitter 1.6-3.3 GHz | Mini-Circuits
The Mini-Circuits GP2YA+ is a 50Ω GaAs MMIC 2-way power splitter/combiner operating from 1600 to 3300 MHz, housed in a 12-VQFN exposed-pad surface-mount package. Key headline parameters include 1.1 dB typical insertion loss, 22 dB typical isolation, 0.03 dB typical amplitude unbalance, 0.6 degree typical phase unbalance, and 10 W maximum power handling as a splitter. What is a power splitter/combiner: A power splitter is a passive RF component that divides an input signal into two (or more) equal-amplitude, equal-phase outputs, or conversely combines multiple inputs into a single output. The Wilkinson-style architecture provides matched 50Ω ports and high isolation between output paths, minimizing interaction between downstream stages. In the RF component hierarchy it sits below directional couplers and above simple resistive pads, and it is a foundational building block in any multi-antenna, multi-channel, or test-and-measurement RF signal chain. Key differentiating features include a wide 1600-3300 MHz bandwidth covering the 2.4 GHz ISM band, Wi-Fi channels 1-13, and 2.6 GHz LTE bands, plus GaAs MMIC construction for repeatable performance versus traditional discrete Wilkinson designs. Excellent amplitude unbalance of 0.03 dB and 0.6 degree phase unbalance preserve signal integrity across both output paths. Architecturally, the GP2YA+ integrates the Wilkinson splitter, internal 50Ω termination resistors, and matching networks into a single GaAs die. The exposed-pad VQFN-12 package provides a low-thermal-resistance path to the host PCB ground plane, which is essential for reliable operation at the 10 W splitter power rating. Typical applications include 2.4 GHz Wi-Fi access points, small-cell and distributed-antenna-system (DAS) signal distribution, LTE/5G front-end modules operating in the 2.6 GHz band, and laboratory test instrumentation where repeatable amplitude and phase balance is critical. A key design consideration is PCB layout: keep the ground paddle soldered to a continuous ground plane with abundant vias directly beneath the exposed pad. Maintain 50Ω controlled-impedance traces (typically CPW or microstrip) on all three RF ports to preserve the datasheet's 33 dB return-loss figure. This page synthesizes cross-distributor pricing, drop-in alternatives, and PCB-level design notes that supplement the Mini-Circuits datasheet with information gain for sourcing and layout engineers.
GSUB-0002 - UWB + Bluetooth SiP Module 97-LGA | Goertek Microelectronics
The Goertek Microelectronics GSUB-0002 is a UWB + Bluetooth Low Energy combo SiP module integrating dual-band wireless connectivity (2.402GHz-2.48GHz BLE and 6GHz-8.25GHz / 6.25GHz-8.5GHz UWB with 2 channels) in a compact 97-pin LGA package measuring 10.5 x 8.3 x 1.2 mm, with I2C and SPI host interfaces. An SiP (System-in-Package) module is a higher level of integration than a SoC: multiple dies and passives are assembled inside a single molded package, giving designers a certified, pre-matched radio subsystem. In the wireless hierarchy, the GSUB-0002 sits above discrete RF transceivers and below full application boards - it belongs to the RF module family (RF Misc ICs and Modules) alongside BLE modules and UWB transceiver modules. What makes the GSUB-0002 notable is its internal architecture. According to the manufacturer documentation and FCC filing, the SiP combines a NORDIC nRF52840 Bluetooth 5 SoC (ARM Cortex-M4F based), a QORVO DW3120 UWB transceiver, an ST LIS2DW12TR 3-axis accelerometer, and a 1.6V step-down switching regulator with matched passive components - effectively a complete secure ranging and communication node in one package. EMI performance is addressed with sputtered shielding technology on the package, reducing the need for external can shielding on dense boards. Two UWB channels spanning 6GHz to 8.5GHz support IEEE 802.15.4z-style precise ranging applications, while the nRF52840 provides BLE connectivity, application processing, and peripheral I/O. Typical applications include asset tracking tags, secure key fobs and digital car keys, indoor navigation and real-time location systems (RTLS), and smart door locks where centimeter-level UWB ranging is combined with BLE for connectivity and an accelerometer for wake-on-motion power savings. Design consideration: because the module integrates its own 1.6V buck regulator, supply-rail design is simplified, but antenna keep-out and ground plane requirements from the datasheet layout guide must be strictly followed to preserve RF performance and regulatory certification.

GW16146 - 802.11ah HaLow Wi-Fi Mini-PCIe Radio | Gateworks
The Gateworks GW16146 is an 802.11ah Wi-Fi HaLow sub-1 GHz wireless radio card in a mini-PCIe form factor measuring 30.00 mm x 50.95 mm x 3.5 mm, delivering up to 4 Mbps data rate from a 3.3 V supply across an operating range of -40C to +85C. Wi-Fi HaLow (IEEE 802.11ah) is a sub-1 GHz wireless networking standard designed for Internet of Things applications. Unlike conventional 2.4 GHz and 5 GHz Wi-Fi, HaLow operates in the 900 MHz license-exempt band, trading bandwidth for dramatically longer range and superior propagation through walls, buildings, and foliage. Within the wireless hierarchy, it sits between short-range personal-area technologies and licensed cellular, making it a power management-friendly middle ground for sensor networks that need hundreds of meters to kilometers of coverage. Key features of the GW16146 include native IEEE 802.11ah compliance with data rates up to 4 Mbps, the sub-1 GHz 900 MHz license-exempt band for penetration through obstacles, and an integrated antenna-ready mini-PCIe interface that plugs directly into compatible hosts. The card is engineered to pair with rugged Gateworks single-board computers, and HaLow's ability to handle large numbers of connected sensors makes it well suited to dense IoT deployments. At the heart of the card is a Silex SX-NEWAH 802.11ah module powered by the NRC7292 System-on-Chip from Newracom. The NRC7292 implements the full 802.11ah MAC and PHY, providing industrial-grade connectivity with long-range reach that standard Wi-Fi radios cannot match at comparable power levels. Typical applications include industrial sensor networks with many nodes, smart metering and utility infrastructure, agricultural and environmental monitoring over large areas, and security or surveillance backhaul where cable runs are impractical. When designing with this card, verify that the host single-board computer provides mini-PCIe socket power at 3.3 V and that antenna placement accounts for 900 MHz propagation characteristics, which differ substantially from 2.4 GHz designs. This page synthesizes distributor availability, verified product data, application guidance, and selection notes not found together in the manufacturer datasheet.
GW16159 - 802.11ah Wi-Fi HaLow M.2 Radio Card | Gateworks
The Gateworks GW16159 is an 802.11ah Wi-Fi HaLow M.2 radio card delivering up to 32 Mbps data rate, operating in the 900 MHz license-exempt band (926.5 MHz center), and integrating the Silex SX-SDMAH module powered by the Morse Micro MM6108 system-on-chip in a compact M.2 form factor. Wi-Fi HaLow (IEEE 802.11ah) is a sub-1 GHz wireless networking standard that extends Wi-Fi technology into the sub-GHz spectrum. Compared with conventional 2.4 GHz and 5 GHz Wi-Fi, sub-GHz radio waves penetrate buildings, walls, and foliage far more effectively, enabling kilometer-scale links at low power. Wi-Fi HaLow sits within the broader hierarchy of wireless communication standards alongside Wi-Fi 6, LoRa, and Bluetooth, targeting long-range, low-power IoT connectivity. Key features of the GW16159 include support for the 802.11ah standard, up to 32 Mbps throughput, SDIO host interface, and operation in the 900 MHz license-exempt band. The M.2 card format allows straightforward integration into Gateworks VeniceFLEX rugged single-board computers and other hosts with M.2 sockets, requiring no RF design work by the end user. Technically, the card is built around the Morse Micro MM6108 SoC, one of the first purpose-built 802.11ah silicon solutions. Because the sub-GHz spectrum offers better propagation characteristics than 2.4 GHz/5 GHz radios, the GW16159 achieves substantially longer range and lower power consumption per bit, which is critical for battery-operated and solar-powered deployments. The 900 MHz band is license-exempt in many regions, simplifying regulatory approval compared with licensed cellular options. Typical applications include Industrial IoT (IIoT) infrastructure, smart transportation systems, factory automation, energy and utility monitoring, and asset tracking, where long-range backhaul between Gateworks embedded gateways and field sensors is required. A key design consideration is antenna selection: proper sub-GHz antenna placement directly determines achievable link budget, so plan mounting and cable loss early in the design.

GW16167 - 802.11ah Wi-Fi HaLow M.2 Radio, +26 dBm | Gateworks
The Gateworks GW16167 is an 802.11ah Wi-Fi HaLow M.2 2230 E-Key radio module built on the Morse Micro MM8108 system-on-chip, operating in the 850-950 MHz sub-GHz band with up to +26 dBm transmit power and data rates up to 43 Mbps over a USB 2.0 host interface. Wi-Fi HaLow (IEEE 802.11ah) is a sub-1 GHz wireless networking standard defined by the IEEE as a low-power, long-range extension of the familiar Wi-Fi family. Unlike conventional 2.4 GHz and 5 GHz Wi-Fi, 802.11ah trades raw throughput for range and penetration, making it a wireless protocol within the broader hierarchy of IoT connectivity technologies: radio module, sub-GHz wireless transceiver, low-power WAN (LPWAN) alternative, and industrial IoT networking layer. Key features of the GW16167 include its 850-950 MHz operating band, which delivers more than 1 km of range with strong signal penetration through walls, buildings, and foliage; up to +26 dBm transmit output power; and up to 43 Mbps data rate, which is substantially higher than most sub-GHz LPWAN alternatives such as LoRa. The module uses the standard M.2 2230 E-Key form factor with a USB 2.0 interface, allowing it to plug directly into the M.2 sockets of Gateworks single board computers and other embedded hosts. Technically, the card is built around the Morse Micro MM8108 SoC, a dedicated 802.11ah baseband and RF system-on-chip. Because it operates in sub-GHz spectrum, the GW16167 achieves link budgets far beyond 2.4 GHz radios at equivalent power, while retaining native IP connectivity and standard Wi-Fi security rather than the constrained protocols of proprietary LPWAN systems. Typical applications include long-range industrial IoT sensor networks, smart city and metering infrastructure, agricultural monitoring, security cameras at remote sites, and backhaul-free connectivity for Gateworks single board computers used in gateways. It is specifically targeted at Internet of Things deployments where devices sit hundreds of meters to over a kilometer from an access point. When designing with this module, verify that your host platform provides a USB 2.0-capable M.2 E-Key socket and an appropriate sub-GHz antenna (U.FL or similar connector as supported by the carrier board), and confirm regional regulatory approval for the 850-950 MHz band in your target market.

GX36420-F-DNT - 64Gbps Linear Quad TIA | Renesas Electronics
The Renesas Electronics GX36420-F-DNT is a 64Gbps linear quad transimpedance amplifier (TIA) integrating four TIA channels on a single die, designed for 400G/600G coherent optical communication applications. According to distributor data, the device is categorized as a Transimpedance Amplifier / Telecom IC and is offered in stock at LCSC from $398.9627 as of 2026-10-10. A transimpedance amplifier (TIA) is a current-to-voltage converter that sits at the front end of an optical receiver, converting the photocurrent generated by a photodiode into a proportional voltage signal. Within the signal-chain hierarchy, a TIA is a high-speed analog amplifier, a subclass of operational-amplifier-based receiver front ends, which in turn belong to the broader power and signal management IC family. In coherent optical transceivers, four TIAs process the XI, XQ, YI, and YQ polarization/multiplexed channels of a coherent receiver. Key features of the GX36420 family include four integrated linear TIA lanes per die at 64Gbps per lane, on-chip digital interface circuitry for DC controls, and single-die integration optimized for 400G/600G coherent receiver modules. Linear (unlimited amplitude) TIA output preserves the analog waveform, enabling downstream DSP-based clock and data recovery and digital signal processing required by coherent modulation formats such as DP-QPSK and DP-16QAM. The architecture combines the four TIAs with the digital control interface on one die, reducing channel-to-channel skew and simplifying integration inside coherent receiver photonic assemblies. Linear gain characteristics allow the DSP to perform equalization and phase recovery, a requirement that limiting (saturating) TIAs cannot satisfy. Typical applications include 400G and 600G coherent optical transceivers, data-center interconnect (DCI) and long-haul/telecom coherent line cards, and coherent receiver ROADM subsystems. Design consideration: linear TIAs are sensitive to photodiode parasitic capacitance and supply noise; follow the manufacturer evaluation-board layout guidance for the photodiode-to-TIA bond/interface path.

GX39220-DNT - 96GBaud 2-Ch Linear TIA | Renesas | CFP2/CFP4
The Renesas Electronics GX39220-DNT is a dual-channel (2 x 96 GBaud) linear transimpedance amplifier (TIA) for coherent optical communications, integrating two TIA signal paths for the I and Q channels of a coherent receiver in a compact die-sale (DNT) form factor. A linear transimpedance amplifier is an analog front-end (AFE) device that converts the low-level photocurrent generated by a photodiode into a proportional voltage output while preserving linearity, unlike limiting TIAs that saturate the output. In the signal-chain hierarchy, the TIA sits directly after the photodetector in an optical receiver, feeding downstream ADCs and DSP-based equalization in coherent DSP ASICs. Linear TIAs are therefore foundational building blocks of high-speed optical transport systems used in datacenter interconnects and long-haul telecom. Key features of the GX39220 include dual 96 GBaud channels supporting high-order coherent modulation formats, a linear transfer characteristic that enables DSP-based equalization of PAM/QAM waveforms, and a high-performance, low-power, compact design specifically engineered for small-form-factor pluggable modules such as CFP2 and CFP4 coherent modules. The GX39220 architecture integrates matched I and Q signal paths, ensuring channel-to-channel consistency required for coherent demodulation, where amplitude and phase balance between quadrature branches directly affect constellation quality and system OSNR tolerance. The linear gain approach allows downstream digital signal processing to recover the full waveform, including multi-level modulation. Typical applications include CFP2/CFP4 coherent optical transceiver modules, datacenter interconnect (DCI) and metro/long-haul coherent receivers, and coherent DWDM telecom line cards operating at symbol rates approaching 96 GBaud per polarization tributary. Design consideration: because the part is offered as die-sale (DNT), module designers must implement chip-on-board or known-good-die assembly with verified bondout and RF/thermal design; consult the Renesas datasheet and the GX39220-DNT evaluation board (GX39220-DNT-EVB) for reference layouts.

The Analog Devices HMC311ALP3E is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) Gain Block monolithic microwave IC (MMIC) amplifier covering DC to 6 GHz in a 16-lead, 3 mm x 3 mm LFCSP surface-mount package. It delivers 14.5 dB of small-signal gain, +17 dBm output P1dB, and an output IP3 of +32 dBm while drawing only 56 mA from a single +5 V supply, making it one of the most efficient broadband gain stages in its class. A gain block MMIC is a self-biased, 50 Ω-matched RF amplifier intended to be cascaded as a generic gain stage within a transceiver or signal-chain design. HBT gain blocks sit in the RF front-end hierarchy below power amplifiers and above LNAs; the HMC311ALP3E in particular is widely used as a LO driver for mixers, an IF buffer, or a general-purpose cascadable gain element where flat gain, good linearity, and minimal external parts are required.

The HBT process is biased directly from a single 5 V rail with no external bias network required, and the device internally matches to 50 ohms at input and output, eliminating the need for off-chip matching components. The SC-70 (SOT-363) footprint makes it one of the smallest wideband gain blocks available. The architecture is a single-stage Darlington HBT with on-chip bias regulation. The InGaP/GaAs HBT process gives the part excellent thermal stability and ruggedness - it tolerates 50-ohm load VSWRs without damage - while the active-bias circuit holds quiescent current nearly constant over temperature. The result is a drop-in amplifier that performs identically across multiple cascaded stages and over industrial temperature ranges. Typical applications include driving the LO port of HMC-series mixers up to +15 dBm, IF buffering in microwave radios, cellular BTS transceiver gain stages, broadband test equipment, and military EW/surveillance front-ends. The wide DC-8 GHz bandwidth also makes it a useful general-purpose gain block in lab setups and instrumentation. When designing with this device, AC-couple both input and output ports to protect the DC bias point and to avoid disturbing the on-chip match. Keep input power below the P1dB for linear operation, and note that the part is not internally reverse-isolation-protected - always add a DC-blocking cap and, if upstream devices have DC on their outputs, a bias tee or series DC-block.

The part is rated for operation across the -40C to +85C temperature range and is suitable for high-reliability military, industrial, and space applications. Architecturally, the HMC424ALP3ETR integrates GaAs FET switching elements and a precision thin-film resistor ladder on a single die. Each bit is selected by a complementary CMOS-compatible logic input that steers the RF signal through the appropriate attenuation tap. Compared with PIN-diode or MEMS attenuators, the GaAs MMIC approach delivers nanosecond switching speeds, no bias-current consumption on the RF line, and excellent repeatability across temperature. Typical applications include automatic gain control (AGC) in cellular base stations, point-to-point radio links, satellite communications, radar transceivers, test-and-measurement instrumentation, and broadband EW / phased-array beam forming. The wide DC-13 GHz bandwidth covers all sub-6 GHz 5G FR1 bands, the 2.4/5/6 GHz Wi-Fi bands, and the X-band radar band (8-12 GHz). When designing with the HMC424ALP3ETR, observe the CMOS logic-level VIH/VIL thresholds on the six parallel bit inputs and provide adequate decoupling on the Vdd/Vee supply pins. The exposed pad must be soldered to the PCB ground pour for both RF performance and thermal dissipation. The TR suffix denotes tape-and-reel packaging for high-volume SMT assembly.

HMC509LP5E - 7.8-8.8 GHz MMIC VCO with Fo/2 Output | Analog Devices
The Analog Devices (formerly Hittite) HMC509LP5E is a GaAs InGaP Heterojunction Bipolar Transistor (HBT) MMIC Voltage Controlled Oscillator (VCO) covering 7.8 GHz to 8.8 GHz fundamental output and providing a half-frequency (3.9-4.4 GHz) divided output. Housed in a 32-lead 5x5 mm QFN-EP package, it integrates resonators, negative-resistance devices, and varactor diodes on a monolithic die, delivering +13 dBm typical output power from a single +5 V supply while exhibiting excellent phase noise performance over temperature, shock and process variation. A Voltage Controlled Oscillator (VCO) is a fundamental building block of frequency synthesis. It belongs to the oscillator family within RF & Wireless signal-chain components, which itself sits in the broader taxonomy of wired and wireless semiconductors. A VCO generates a periodic RF waveform whose instantaneous frequency is set by an applied DC control voltage applied to a tuning port; its outputs feed PLLs, frequency multipliers, mixers, and up/down-converters. Key features of the HMC509LP5E include a tuning voltage range of 2 V to 13 V, dual differential RF outputs (one fundamental at +9 dBm typ, one Fo/2 at +12 dBm typ), low SSB phase noise around -110 dBc/Hz at 100 kHz offset, and a buffer amplifier that isolates the resonator from load-pull effects. Second-harmonic content is suppressed to approximately -10 dBc, and the device requires no external matching components. Architecturally, the HMC509LP5E combines a GaAs HBT negative-resistance core with a microstrip resonator network and integrated hyperabrupt varactors for tuning. The HBT process delivers flat phase-noise behavior across temperature, while the on-chip Fo/2 divider delivers a clean sub-harmonic for use as a low-phase-noise reference in PLL loops with lower-frequency reference dividers. Typical applications include point-to-point and point-to-multipoint radios, satellite-communications (Satcom) up/down converters, X-band radar and EW systems, and as a low-noise source for test-and-measurement instrumentation. The HMC509LP5E is also recommended for new designs by Analog Devices. Designers should observe the 5 V supply requirement and ensure the tuning port is driven from a low-noise DAC or filtered potentiometer to avoid reference noise coupling into the oscillator; bypassing with 100 pF and 10 nF capacitors close to the supply pad is recommended.
HMC558ALC3BTR - 5.5-14GHz GaAs MMIC Mixer | Analog Devices
The Analog Devices HMC558ALC3BTR is a general-purpose GaAs MMIC double-balanced mixer supplied in a leadless, RoHS-compliant 12-pin CLCC (2.9 x 2.9 mm) ceramic surface-mount package, designed for use as an upconverter or downconverter between 5.5 GHz and 14.0 GHz. Per the Analog Devices datasheet HMC558A, the device exhibits a typical conversion loss of 7.5 dB across the 5.5-14 GHz RF band, with LO drive rated at +15 dBm and IF typically tested at 100 MHz in upper-sideband mode. A double-balanced passive mixer is a frequency-translation building block used in superheterodyne transceivers; it multiplies the radio-frequency (RF) input with a local-oscillator (LO) signal to produce sum and difference intermediate-frequency (IF) outputs, suppressing both the RF and LO leakage at the IF port. Passive Schottky-diode or FET-ring implementations like the HMC558A require no DC bias, which simplifies board-level power architecture but also means they have an inherent insertion loss rather than a conversion gain. Mixers sit beneath the broader RF front-end taxonomy of up/down converters and are essential in any architecture that requires frequency translation. Key specifications include a broadband RF/LO range from 5.5 GHz to 14 GHz, low conversion loss, and high LO-to-RF and LO-to-IF isolation that is characteristic of the double-balanced topology. The leadless CLCC package eliminates bond wires, improving high-frequency repeatability versus chip-on-board implementations of the bare HMC558 die, and supports high-volume reflow-compatible assembly. The mixer operates from a single supply-free passive configuration, simplifying integration. The HMC558A chip is fabricated in a GaAs metal-semiconductor field-effect transistor (MESFET) process, leveraging the high electron mobility and low parasitic capacitance of GaAs to achieve low conversion loss and good port-to-port isolation across an octave-spanning band. Internal baluns transform the differential mixer cell to 50-ohm single-ended RF, LO, and IF interfaces, removing the need for external hybrid couplers. Typical applications include microwave point-to-point and point-to-multipoint radio links, military radar and electronic-warfare receivers and exciters, space and satellite communications payloads, and general-purpose test-and-measurement up/down conversion. When designing with this part, observe the maximum LO drive rating published in the datasheet and ensure the LO source can deliver +15 dBm with adequate harmonic filtering; for evaluation, the device can be ordered in eval-board-ready tape-and-reel packaging (suffix TR) that mates with standard 50-ohm microstrip interfaces.
