WVBP-733-WR12+ - 71-76 GHz WR12 Waveguide BPF | Mini-Circuits
The Mini-Circuits WVBP-733-WR12+ is a rectangular waveguide bandpass filter covering 71 to 76 GHz in the E-band millimeter-wave spectrum, housed in a WR12 (WG26 / R740) waveguide interface with case style TH2793. Per the Mini-Circuits/Everything RF product listing, the part delivers 0.6 to 1 dB typical insertion loss across the passband and 20 to 94 dB of rejection outside-band, designed jointly with Virginia Diodes for high-fidelity millimeter-wave metrology. A waveguide bandpass filter is a passive RF component that uses precisely machined resonant cavity structures inside a hollow metallic waveguide to selectively transmit a defined frequency band while reflecting out-of-band energy. As a subclass of bandpass filter, waveguide BPFs offer much lower insertion loss, higher Q, and superior power handling at millimeter-wave frequencies compared to microstrip or coaxial cavity filters, because air is the dielectric and the walls carry the currents. In the system hierarchy, this part sits within E-band wireless front-ends, millimeter-wave test instrumentation, and 71-76 GHz point-to-point radio links. Key specifications include the 5 GHz passband (71-76 GHz), typical 0.6 to 1 dB in-band insertion loss, a worst-case rejection figure spanning 20 to 94 dB depending on stopband location, and a standard WR12 flange interface compatible with UG-387/U-M style round flanges. The product carries an environmental rating of ENV80 per the Mini-Circuits WebStore technical notes and uses a RoHS-compliant plating per the material declaration. Mechanical tolerances are described by Mini-Circuits as precise machine tolerances with quality plating for long-term performance. Typical applications include 71-76 GHz E-band point-to-point backhaul radio transmitters and receivers, automotive 76-81 GHz short-range radar front-end filtering (when the upper 5 GHz slice of E-band is selected), millimeter-wave test-and-measurement setups including spectrum analyzer image rejection, and laboratory research in 6G / sub-THz channel propagation. The 71-76 GHz window is the lower half of the FCC/EU-allocated E-band and is widely used for carrier-grade wireless backhaul. When integrating this filter, flange alignment and torque are critical - the WR12 aperture is small (3.099 mm × 1.549 mm), and a misaligned flange or under-torqued screws will leak past-band energy into the system. Always use a calibrated millimeter-wave torque driver and a fresh gasket (or precision-machined shims) per the Mini-Circuits technical note AN75-004.

WVBP-783-WR12+ - 76-81 GHz WR12 Waveguide Bandpass Filter | Mini-Circuits
The Mini-Circuits WVBP-783-WR12+ is a rectangular waveguide bandpass filter covering 76,000 to 81,000 MHz in a WR12 waveguide flange, designed in collaboration with Virginia Diodes for millimeter-wave metrology-grade performance. A waveguide bandpass filter is a passive RF component that selects a defined frequency band inside a hollow metallic waveguide while rejecting out-of-band energy. In the system hierarchy it sits between antenna/RF front-end modules and the down-conversion or transceiver chain, providing pre-select filtering that protects sensitive receivers from adjacent-channel interference and out-of-band blockers. Waveguide structures are favored at millimeter-wave frequencies because they exhibit very low loss compared to microstrip or stripline at the same wavelengths. Key features include a passband of 76-81 GHz, insertion loss between 0.6 and 1.5 dB, rejection of 20 to 91 dB depending on offset frequency, and operating temperature range of -40 to +85 C. The filter uses the WR12 standard rectangular waveguide interface (also designated as WG26 / R740 per IEC 60154), making it compatible with mainstream E-band test bench hardware and millimeter-wave instrumentation. The case style is TH2793 with environmental rating ENV80 per the manufacturer datasheet. Technical depth: the WVBP-series filters leverage Virginia Diodes' precision-machined resonator cavities, offering high Q-factor and excellent roll-off steepness. The construction produces consistent repeatable mode and superior quality plating for long-term stability in laboratory and production environments. Typical 3 dB bandwidth and 1 dB bandwidth figures are specified in the per-model data sheet. Typical applications include E-band (71-86 GHz) telecommunications links, automotive 77 GHz radar test, millimeter-wave instrumentation, 5G FR2+ test and measurement, and satellite payload filtering. The filter is engineered for metrology-grade measurement benches and production ATE where repeatable insertion loss and high out-of-band rejection are critical. When designing with this part, ensure the waveguide flange surface is clean and that UG-387/U-M precision flanges and screws are torqued to spec to avoid flange leakage at 80 GHz, where even small gaps introduce measurable loss. Use a calibrated vector network analyzer with appropriate millimeter-wave test heads when verifying S-parameters.

WVBP-833-WR12+ - WR12 Waveguide BP Filter 81-86 GHz | Mini-Circuits
The Mini-Circuits WVBP-833-WR12+ is a rectangular waveguide bandpass filter covering the 81 to 86 GHz E-band frequency range, with insertion loss between 0.5 and 1 dB and rejection levels from 20 to 90 dB. The part uses the WR12 waveguide interface and operates over a -40 °C to +85 °C temperature range per its ENV80 environmental rating. The product is built on the Virginia Diodes metrology-grade heritage that Mini-Circuits now extends to millimeter-wave and terahertz customers. A waveguide bandpass filter is a passive RF/microwave component that passes a defined frequency band while rejecting signals outside that band. Waveguide filters belong to the RF filter family (bandpass, bandstop, low-pass, high-pass) and sit within the broader RF passives hierarchy above connectorized components but below active transceivers. WR12 designates the EIA-standard rectangular waveguide size whose internal dimensions are calibrated for the 60-90 GHz millimeter-wave band, making these filters the natural choice for E-band backhaul, 5G FR2+ research, and automotive 76-81 GHz radar prototyping. Key features of the WVBP-833-WR12+ include 81-86 GHz passband coverage suited to E-band wireless links, 0.5-1 dB low insertion loss to preserve link margin, 20-90 dB rejection for clean spurious suppression, the industry-standard WR12 flange interface, and the case style TH2793 housing. The housing typically uses precision-machined split-block construction that ensures repeatable mechanical and electrical performance. The internal architecture uses cascaded waveguide resonator sections that are designed and validated by Virginia Diodes metrology team, leveraging more than a decade of terahertz instrumentation experience. The filter is processed as a single metal block, avoiding the dielectric-loss penalties and radiation-leakage paths that limit microstrip or stripline implementations at these frequencies. Typical applications include E-band point-to-point backhaul links where the 81-86 GHz band aligns with the light-licensing 5G and 6G research bands, automotive radar prototyping around 76-81 GHz, millimeter-wave test instrumentation and bench setups, and terahertz imaging / spectroscopy front-ends. Designers choose waveguide filters here because PCB-based filters exhibit prohibitive loss above 60 GHz. Design consideration: account for flange alignment torque and UG-387/U flange hardware when budgeting assembly tolerance. Mating flange flatness of 0.0005 inch or better is recommended to prevent passive intermodulation and leakage at these frequencies.

XB3-24Z8PT-J - XBee 3 2.4GHz Zigbee 3.0 TH Module | Digi
The Digi XB3-24Z8PT-J is a Digi XBee 3 series 802.15.4 Zigbee 3.0 transceiver module operating at 2.4 GHz with an integrated PCB trace antenna in a through-hole mounting form factor. The module is built around the Silicon Labs EFR32MG SoC and supports a serial data rate up to 1 Mbps with a 250 kbps RF data rate, while operating from a single 2.1 V to 3.6 V supply. It uses the same TH (through-hole) footprint as legacy XBee S2C modules, providing a true drop-in upgrade path. A wireless transceiver module is a pre-certified, surface-mount or through-hole assembly that integrates an RF transceiver IC, matching network, antenna, and sometimes an onboard microcontroller. These modules live in the broader category of RF & Wireless components, sit below wireless modules, and above bare RF transceiver ICs. They simplify wireless product certification because the radio has already been tested against regional regulatory standards (FCC, IC, ETSI, etc.), allowing end products to inherit the modular certification. Key features include receiver sensitivity of -103 dBm, an integrated PCB antenna, UART/SPI/I2C host interfaces, ADC and PWM I/O, and Zigbee 3.0 mesh protocol support with Digi's MicroPython programmability. The module's transmit output power is approximately +8 dBm (regular XBee 3, not the PRO variant) and the RF data rate is 250 kbps. The through-hole pin layout allows simple socketed or soldered mounting on 2 mm-pitch through-hole pads. Technically, the module combines the EFR32MG ARM Cortex-M4 SoC with an integrated 2.4 GHz radio, an RF front-end with balun, a PCB trace antenna, and onboard LDO regulators supporting the 2.1 V to 3.6 V input range. Digi provides a unified XBee API mode and AT command set across the XBee 3 family, so firmware written for an XBee 3 SMT module will migrate directly to the TH version with no host-side changes. Typical applications include industrial IoT sensor mesh networks, building automation (HVAC, lighting, occupancy), smart energy metering, asset tracking, and wireless remote-control links where Zigbee mesh topology adds self-healing multi-node coverage. The form factor is favorable: the same TH footprint across XBee generations allows customers to upgrade from older XBee S2C modules without PCB rework. When designing with this module, pay attention to antenna keep-out: do not place copper, ground planes, or plastic with high dielectric loss within the PCB antenna's keep-out area, as it will detune and degrade the link budget. Also confirm that the host MCU supplies 3.3 V logic on UART lines, because the module's GPIO is not 5 V tolerant.

XB3-24Z8UM - XBee 3 PRO Zigbee 3.0 Micro U.FL MMT Module | Digi
The Digi XB3-24Z8UM is a Digi XBee 3 PRO Zigbee 3.0 surface-mount RF transceiver module operating in the 2.4 GHz ISM band with a U.FL antenna connector (antenna not included) and MMT (Micro Mount) form factor. Built on the Silicon Labs EFR32MG SoC, it delivers up to 8 dBm (PRO) transmit power and supports the IEEE 802.15.4 / Zigbee 3.0 protocol stack at over-the-air RF data rates up to 250 kbps with serial interface rates up to 1 Mbps. An RF module (radio-frequency module) is a small PCB sub-assembly that integrates a wireless transceiver IC, matching network, crystal, and antenna interface into a single, EMC-compliant package. RF modules sit in the wireless connectivity hierarchy below discrete transceivers and above raw silicon ICs, abstracting RF design complexity so that MCU-based host boards can add wireless capability with a simple UART/SPI/I2C interface. The XB3-24Z8UM belongs to the XBee 3 PRO family, which adds extended RF link budget (PRO = higher TX power, lower RX sensitivity threshold) for longer-range mesh deployments. Key features of the XB3-24Z8UM include 8 dBm (PRO) TX power, 2.4 GHz worldwide ISM band operation, Zigbee 3.0 mesh networking support, and a wide -40C to +85C industrial operating temperature range. The module integrates a Silicon Labs EFR32MG SoC with on-board microcontroller, eliminating the need for an external host MCU in many edge-IoT designs. UART, SPI, and I2C host interfaces are exposed through the 34-pin MMT land pattern. The U.FL RF connector enables use of an external antenna selected for the deployment enclosure. Typical applications include building automation nodes, smart lighting controllers, smart energy metering, digital health peripherals, industrial sensor mesh networks, and any IoT device requiring certified multi-vendor Zigbee 3.0 interoperability. The XBee 3 platform is supported by Digi's XCTU configuration tool and Digi Remote Manager cloud integration, simplifying provisioning and OTA firmware updates. When designing with this module, note that antenna selection is critical - although the U.FL connector is present, RF performance depends entirely on the chosen external antenna, its placement, and ground plane clearance. Allow at least 5 mm of keep-out under the antenna feed trace, follow the MMT footprint exactly, and avoid placing the module near large metal planes that detune the antenna.
XB3-24Z8UM-J - XBee 3 Zigbee 3.0 Module, 2.4 GHz, U.FL Antenna | Digi
The Digi International XB3-24Z8UM-J is a compact surface-mount XBee 3 Zigbee 3.0 transceiver module operating in the 2.4 GHz ISM band, housed in a 34-pin SMD Micro form factor with a U.FL antenna connector (antenna not included). It integrates the Silicon Labs EFR32MG SoC and supports 802.15.4 with a native RF data rate of 250 Kbps and a serial interface rate up to 1 Mbps. The module accepts a 2.1 V to 3.6 V supply, draws sub-microamp sleep currents, and provides UART, SPI, and I2C host interfaces for flexible integration into micro-controlled or hostless designs. A Zigbee module is a pre-certified, drop-in radio subsystem that bundles an RF transceiver IC, crystal, matching network, and PCB antenna or U.FL connector onto a single castellated PCB. XBee modules sit in the broader category of embedded wireless modules, above discrete RF transceivers and below complete IoT gateways. They are widely used to add Zigbee, Thread, or Bluetooth connectivity to a host MCU without requiring the designer to handle RF layout, FCC certification, or mesh protocol stacks. The XBee 3 family specifically combines Zigbee 3.0 with Bluetooth Low Energy (BLE) for provisioning and supports MicroPython for on-module scripting. Key features of the XB3-24Z8UM-J include an integrated Silicon Labs EFR32MG SoC, DSSS spread-spectrum modulation for robust 2.4 GHz operation, an operating temperature range that supports industrial deployment, and an ultra-low sleep current that suits battery-powered wireless sensor nodes. The U.FL antenna variant allows designers to attach an external antenna for enclosures where an on-module chip antenna would suffer detuning. The Micro form factor keeps the module footprint roughly 13 mm × 19 mm, enabling dense IoT endpoint designs. From an architectural standpoint, the XB3-24Z8UM-J separates the radio domain (EFR32MG SoC + RF frontend + shield can) from the host domain (UART/SPI/I2C). The on-board ARM Cortex-M4F core runs the Zigbee 3.0 stack and optional MicroPython, while the host MCU exchanges AT commands or API frames. This split keeps the host firmware simple and shields the application processor from real-time RF stack management. Typical applications include Zigbee wireless sensor networks for smart buildings, industrial telemetry, smart lighting and home automation, asset tracking, and battery-powered remote controls. The combination of low sleep current, mesh networking, and MicroPython programmability suits edge-deployed sensor nodes with infrequent wake cycles. For projects requiring an external antenna placement (for example, inside a metal enclosure), the U.FL variant is the correct choice; for exposed-product designs, the chip-antenna variant (XB3-24Z8CM-J) may be preferred. When designing with the XB3-24Z8UM-J, ensure the host board provides a stable 3.3 V rail capable of peak transmit current bursts (about 130 mA typical) and that the U.FL antenna cable is kept short and away from noise sources. The castellated edge pads require clean solder paste printing and a reflow profile compatible with the integrated shield can; hand-soldering the module is not recommended. Always confirm regional Zigbee channel selection against local regulations (Wi-Fi coexistence considerations in the 2.4 GHz band).

ZED-X20D-00B - All-Band Dual-Antenna GNSS RTK Module | u-blox
The u-blox ZED-X20D-00B is an all-band, high-precision, dual-antenna GNSS heading module with a tracking sensitivity of -167 dBm, packaged in a 54-pin LGA (22×17 mm) surface-mount form factor. It delivers centimeter-level RTK positioning and precise attitude (heading) information by simultaneously exploiting all major GNSS constellations, including GPS, GLONASS, BeiDou, Galileo, QZSS, and NAVIC. An all-band GNSS receiver is a positioning radio that simultaneously tracks the L1, L2, L5, L6 and similar carrier frequencies broadcast by every major satellite navigation system. Compared with single-band (L1-only) modules, an all-band receiver resolves the ionospheric delay error that otherwise limits horizontal accuracy to roughly one to three meters, enabling real-time kinematic (RTK) fixes at centimeter precision. The ZED-X20D belongs to u-blox's professional-grade X20 platform, targeting OEM integrators of robotics, autonomous vehicles, precision-agriculture machinery, and other industrial systems that demand sub-degree heading plus RTK position from two antennas on a single moving platform. Key features include concurrent reception across all GNSS bands with multi-band RTK engine support, on-board dual-antenna heading computation that works at standstill (motion-independent), built-in jamming/spoofing detection, Root of Trust secure boot, and cryptographic Galileo OSNMA authentication of navigation messages. The module supports both Base and Rover modes, enabling customers to use a single SKU for the reference-station side of an RTK link as well as the mobile side. The 54-pin LGA footprint is pin-compatible with the higher-tier ZED-X20P, allowing designers to scale between heading and dual-frequency positioning variants without board rework. Architecturally, the ZED-X20D integrates an RF front-end, a multi-band GNSS baseband, a 32-bit application processor running u-blox's positioning firmware, and hardware accelerators for RTK and PPP convergence. The use of a dedicated heading engine reduces the time-to-first-fix for attitude and lets the firmware output yaw, pitch, and roll on a separate message stream alongside the position fix, with a heading update rate up to 10 Hz in the default firmware. Typical applications include precision-agriculture tractor and implement guidance, unmanned autonomous vehicles (UAVs and ground robots), construction and mining machine control, harbor and rail asset tracking, and surveying equipment. For drones and rovers, the headline benefit is robust heading even at zero velocity, which eliminates magnetometer drift on small platforms and short antenna baselines down to 50 cm. When designing with this part, allocate a 22×17 mm keep-out area on the top layer for the LGA and route the two antenna feeds (ANT1, ANT2) as short 50-ohm controlled-impedance traces, keeping both SAW filters and LNA close to the module pins to preserve phase coherence needed for accurate heading.

ZOE-M8B - Ultra-Low Power GNSS SiP Module | u-blox
The u-blox ZOE-M8B is an ultra-small, super-low-power GNSS System-in-Package (SiP) module with Super-E mode, integrating a u-blox M8 GNSS receiver, TCXO, SAW filter, and LNA in a 4.5 x 4.5 x 1.0 mm S-LGA package. It supports concurrent reception of up to three GNSS systems (GPS, Galileo, GLONASS, BeiDou) with a tracking sensitivity down to -160 dBm and power consumption as low as 12 mW in Super-E mode. What is a GNSS SiP? A GNSS (Global Navigation Satellite System) System-in-Package (SiP) integrates the entire satellite positioning receiver chain — RF front end, baseband processor, memory, and crystal — into a single surface-mount module. GNSS SiPs occupy the same system hierarchy as GNSS receiver ICs and modules, both subclasses of RF & Wireless > GNSS Modules, providing complete positioning solutions without the design effort of discrete RF layout. Key features include concurrent multi-GNSS reception across GPS L1, Galileo E1, GLONASS L1, and BeiDou B1 bands; integrated SAW filter and low-noise amplifier for passive-antenna operation; 25 mW average power over a typical 30-minute track; anti-jamming and anti-spoofing message integrity protection; and pin-to-pin compatibility with the predecessor ZOE-M8G. The Super-E mode delivers approximately 2.5x lower power than full-power operation while maintaining good positioning and speed accuracy. Technically, the ZOE-M8B is built on u-blox's M8 positioning engine with 72-channel architecture, ROM firmware, and a built-in TCXO for fast satellite acquisition. Communication is via UART, I2C, or SPI digital interfaces. The integrated dual-frequency RF front-end allows either GLONASS or BeiDou to be processed concurrently with GPS and Galileo, enabling simultaneous reception of three GNSS systems for faster, more accurate fixes. Typical applications include wearable fitness trackers, asset trackers, smart watches, IoT sensor nodes, and portable navigation devices where battery life and compact PCB area are critical. The 4.5 x 4.5 mm footprint and 12 mW Super-E power also suit disposable or energy-harvesting designs. Designers should note the ZOE-M8B is an older-generation product; u-blox recommends the MIA-M10 series for new designs. When migrating from ZOE-M8G, verify the minor differences in the SIM report (UBX-17045131) to ensure compatibility. Provide a clean 1.8V supply rail and follow u-blox's reference layout to maintain RF performance.
ZX60-362LN-S+ - 3.3-3.6GHz Low-Noise Amplifier SMA Module | Mini-Circuits
The Mini-Circuits ZX60-362LN-S+ is a connectorized low-noise, linear RF amplifier covering 3300 MHz to 3600 MHz in a chassis-mount SMA module optimized for 50 ohm systems. Headline parameters include 9.0 to 11.5 dB gain, 0.9 to 1.2 dB noise figure, and P1dB of 8.5 to 10.5 dBm, all packaged in a 50 ohm SMA coaxial housing that requires no external matching network. A low-noise amplifier (LNA) is an RF amplifier placed at the front-end of a receiver chain immediately after the antenna, designed to add minimal noise while providing enough gain to set the system noise floor before subsequent filtering and downconversion stages. LNAs sit within the broader hierarchy of RF/microwave amplifiers -> amplifier ICs -> RF & wireless integrated circuits -> semiconductors, and are characterized by noise figure, gain, linearity (P1dB, IP3), input/output return loss, and unconditional stability. Compared with general-purpose gain blocks, LNAs prioritize noise figure and input match over raw output power. Key features of the ZX60-362LN-S+ include ±0.5 to ±1.0 dB gain flatness across the band, 1.4:1 typical input and output VSWR, +5 V single-supply operation, and unconditional stability per US patent 6,943,629. The connectorized SMA housing simplifies lab evaluation, drop-in module replacement, and reference design prototyping without the layout complexity of bare-die or surface-mount MMIC integration. The 3.3 to 3.6 GHz band directly covers WiMax and 3.5 GHz radar / fixed wireless allocations. The internal amplifier die uses a GaAs pHEMT process topology common to Mini-Circuits' ZX60 connectorized lineup, with internal 50 ohm matching networks and DC blocking on the RF path. Internal regulation provides supply-noise immunity, and the module includes reverse-voltage protection. S-parameter data files in Touchstone and View PDF formats are available from Mini-Circuits' website, supporting direct import into RF simulation tools such as Keysight ADS, Cadence AWR, and Ansys HFSS. Typical applications include 3.5 GHz WiMax subscriber equipment, 3.3 to 3.6 GHz radar front-end LNA stages, S-band telemetry and point-to-point radio receivers, base-station receive chains, and laboratory reference / evaluation platforms where a connectorized LNA is preferred over a surface-mount MMIC. When designing with this module, use a regulated +5 V supply with adequate bypass (100 nF + 10 uF) on the bias pin to prevent noise injection through the DC feed, and verify S-parameters against your system's noise and gain budget using Mini-Circuits' Touchstone files. This page synthesizes distributor pricing, connectorized-module cross-references, and practical front-end design notes not found in the manufacturer datasheet.
