A superheterodyne image-reject receiver is a radio-frequency architecture that converts the incoming RF signal to an intermediate frequency in two stages while using an image-reject mixer to suppress the mirror frequency, reducing the need for expensive front-end SAW filtering. Within the power-management hierarchy of a wireless link, such receivers sit between the antenna/LNA stage and the digital baseband, making them a core component of low-power RF front ends for remote-control and telemetry systems. Key features include multi-band operation across three ISM ranges (302-320 MHz, 433-450 MHz, and 865-870 MHz), support for both ASK and FSK demodulation, and integrated digital baseband processing for Manchester-coded data signals. The image-reject mixer architecture lowers external component count, while the low-power design targets battery-operated transmitter-receiver links such as keyless entry and remote sensors. Technically, the TDA5230 performs single-conversion superheterodyne reception with multi-channel synthesizer-based tuning, allowing firmware selection of channels within the supported bands. The on-chip digital baseband handles data slicing and Manchester decoding, offloading the host microcontroller and improving tolerance to noise and frequency drift. Typical applications include 433 MHz and 868 MHz remote keyless entry receivers, home and building automation nodes, low-power telemetry in the 315/433/868/870 MHz ISM bands, and wireless sensor read-outs. Design consideration: the image-reject and channel-filter settings must be configured to match the chosen band and data rate; verify crystal and reference frequency planning against the datasheet before locking the PCB layout.

(formerly Maxim Integrated) VSC7158HT-03 is a high-performance 8-port Fast Ethernet PHY transceiver supporting 10BASE-T and 100BASE-TX, packaged in a surface-mount IC form factor for managed switch and router line-card applications. The device integrates eight independent physical-layer blocks, each capable of full-duplex 100 Mb/s operation with auto-negotiation and auto-MDI/MDIX crossover, while consuming low per-port power typical of CMOS PHY designs. A Fast Ethernet PHY (Physical Layer Device) is the lowest layer of the OSI networking stack; it converts parallel digital MAC-side data into serialized analog symbols transmitted over copper twisted-pair cabling, while recovering the clock and decoding incoming symbols on the receive side. The PHY sits beneath the MAC (Media Access Controller) and above the magnetics/transformer interface, forming the bridge between digital logic and the analog copper channel. For 100BASE-TX, the line code is 4B/5B MLT-3 over Cat-5 cable; for 10BASE-T, Manchester encoding is used on the same physical medium. Multi-port PHYs integrate several of these transceivers into one package, simplifying PCB layout and BOM for managed switches. Key features of the VSC7158HT-03 include integrated termination, baseline wander compensation, on-chip transmit waveform shaping, and per-port link/status LEDs. It exposes a Media Independent Interface (typically MII or RMII) toward the MAC, and supports standard 802.3u Clause 28 auto-negotiation. The device is designed for non-blocking 8-port switching fabrics in workgroup switches, NICs, and embedded networking platforms. Architecturally, the part uses mixed-signal CMOS with embedded DSP-based echo and crosstalk cancellers. Its multi-port integration eliminates the need for eight discrete PHY ICs, reducing board area, BOM cost, and the FPGA/CPLD glue logic typically associated with dispersed PHY designs. Designers can therefore achieve higher port density in 1U rack-mount switches without redesigning the analog front end. Typical applications include 8-port workgroup Ethernet switches, router LAN interfaces, industrial Ethernet bridges, network interface cards, and IP surveillance switching planes. Its per-port low power also suits fanless embedded networking appliances. When designing with this part, verify reference clock quality, magnetics isolation, and proper 50 Ω-impedance routing on the MII bus. Because the part is mature and distribution-constrained, validate long-term availability before committing to new designs. This page synthesizes distributor pricing, lifecycle status, application context, and practical design considerations that are not consolidated on any single distributor listing for the VSC7158HT-03.

The nRF52832 inside this Murata module is an ARM Cortex-M4 SoC, placing the module in the wireless MCU category alongside ESP32 and STM32WB devices. Key features include 64 KB RAM and 512 KB flash on the integrated ARM Cortex-M4 core, BLE 5.0 long-range and 2 Mbps PHY support, and a regulated 1.7-3.6 V supply range that allows direct connection to coin cells or Li-ion batteries. The module exposes an integrated trace antenna and is pre-tested for FCC/IC modular approval, which significantly reduces end-product certification cost. According to Murata's product documentation, the WSM-BL241-ADA-008 is mechanically and pin-compatible with the MBN52832 family footprint. Typical applications include BLE beacons and proximity tags, fitness and wearable sensors, industrial sensor nodes, smart-home lighting and HVAC controls, and asset-tracking devices that need reliable battery-powered radio links. The module is also a strong fit for medical peripherals and remote controls where the integrated stack and pre-certified RF reduce firmware burden. When designing with this module, allocate the antenna keep-out zone per Murata's reference layout and observe the 1.7-3.6 V supply limit; adding a 10 uF bulk plus 0.1 uF bypass capacitor near VDD is recommended. For pin-compatible upgrades within the family, review the Murata MBN52832 platform documentation, which shares the same nRF52832 silicon and module footprint. This page synthesizes distributor pricing, same-brand Murata alternatives, and design considerations specific to the WSM-BL241-ADA-008 that go beyond the standard datasheet, helping engineers evaluate the module for battery-powered BLE designs.

The kit operates in the 2.4 GHz ISM band, supports Bluetooth 5.x (BLE) protocol, and is delivered as a ready-to-use development board with onboard U.FL connector for RF measurements and trace antenna option. A Bluetooth Low Energy development kit is a hardware platform that allows engineers to prototype, evaluate, and certify wireless products without designing RF circuitry from scratch. Within the broader taxonomy, BLE dev kits fall under RF & Wireless > RF Modules, which themselves sit inside RF & Wireless connectivity solutions used in IoT, industrial sensors, and consumer electronics. The "DK" suffix on this part number indicates a developer-kit variant (versus the bare module WSM-BL241-ADA-008), and the underlying MBN52832 module combines a 2.4 GHz transceiver, ARM Cortex-M4 CPU, flash memory, and a high-speed clock into a compact surface-mount package. Key features of this kit include Bluetooth v5.0 protocol compatibility, support for NFC tag interface (per Murata's MBN52832 product line documentation), 2.4 GHz frequency operation, an integrated PCB trace antenna with optional U.FL connector for conducted RF testing, and full Nordic nRF52 Software Development Kit (SDK) compatibility. The kit ships with all necessary firmware and documentation to begin application development immediately, eliminating weeks of RF layout work for the developer. Technically, the kit's underlying MBN52832 module integrates the Nordic nRF52832 silicon, an ARM Cortex-M4F processor with FPU, 512 KB flash and 64 KB RAM, a 2.4 GHz radio supporting BLE 5.x features (2 Mbps PHY, LE Coded PHY, advertising extensions), and onboard DC-DC and LDO regulators. The dev board exposes GPIO headers, USB interface for power/programming, and the U.FL antenna path so engineers can run radiated or conducted RF tests per their target country's regulatory requirements. Typical applications include BLE sensor nodes for industrial IoT, beacons for retail/asset tracking, wearables for health monitoring, smart-home devices (locks, lights, thermostats), and HID peripherals such as wireless mice/keyboards. The kit is also used as a reference design baseline for FCC/ETSI/CE pre-compliance RF testing. When designing with this kit, engineers should note that the U.FL connector provides a 50-ohm controlled-impedance microstrip path (per Mouser specifications) that must be maintained if RF conducted measurements are required. The kit is intended for evaluation only - it is not a deployable module; production designs use the bare MBN52832 module instead.
WSSFM10R1 - Wisol Sigfox RCZ1 Module 13x15mm | Sub-1GHz LPWAN
The Wisol WSSFM10R1 is a miniaturized Sigfox-only mode RF module measuring 13.0 x 15.0 x 2.21 mm, designed for RCZ1 (Europe, Middle East, Africa) plus RCZ6 (India) and RCZ7 (Russia) regional Sigfox operation. It integrates an on-board MCU and an integrated RF transceiver, exposes UART for external host communication, and uses a TCXO for tight frequency tolerance across operational bands. The module ships in a 31-pin SMD land-grid footprint rated for tape-and-reel packaging and is targeted at sub-1 GHz ultra-narrow-band IoT links where Sigfox is the chosen LPWAN. A Sigfox module is a pre-certified sub-GHz radio plus protocol-stack module that abstracts the physical and MAC layers of the Sigfox LPWAN so the host MCU only needs to issue AT commands over UART. Sigfox modules sit below the application MCU and above the bare RF transceiver in the connectivity hierarchy (Sigfox module -> sub-GHz LPWAN module -> wireless module -> IoT connectivity IC -> semiconductor). They are favored for asset tracking, smart sensors, smart buttons, and metering endpoints because the radio is pre-tuned and the protocol stack is pre-licensed. Key features of the WSSFM10R1 include Sigfox-only protocol operation, integrated TCXO for frequency stability, UART command interface, 31-pin SMD land-grid package, and pin-to-pin compatibility across the RCZ1/RCZ2/RCZ3/RCZ4 Wisol Sigfox family per the manufacturer datasheet. The module is built around an OnSemi AX-Sigfox transceiver implementation, which simplifies customer designs by eliminating the discrete RF matching network normally required for Sigfox CE compliance. The architecture pairs an OnSemi Sigfox modem SoC with a TCXO reference, antenna RF chain, and power-tree filtering, all routed to the host through a UART bridge. Module firmware exposes the AT command set; GPIO2 and GPIO3 are reserved as "Not connected" on RCZ2/RCZ4-compatible variants and unused on RCZ1 SKUs. Typical applications include Sigfox asset tracking, animal tracking tags, smart metering endpoints, smart city sensors, push-button remote controls, and healthcare wearables. The Wisol WSSFM10R1 is well-suited whenever a low-data-rate, ultra-low-power uplink is required and the deployment region falls inside the RCZ1, RCZ6, or RCZ7 Sigfox coverage zones. When designing in this part, mount the module on a PCB with a 50-ohm controlled-impedance antenna trace to the chip antenna or external antenna connector, keep the TCXO area clear of thermal gradients, and confirm regional Sigfox zone membership (RCZ1) before committing the BOM. The WSSFM10R1 is also distinguished from the WSSFM10R1AT AT-command variant by its firmware image - both share the same 31-pin SMD footprint. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone.
WSSFM10R1AT - Sigfox RCZ1 868MHz AT-Command RF Module | WISOL/SeongJi
The WISOL/SeongJi WSSFM10R1AT is a compact Sigfox RCZ1-compliant, AT-command-controlled sub-1 GHz RF transceiver module measuring 13.0 mm x 15.0 mm x 2.21 mm in a 31-pin SMD package. It is designed for Europe/ETSI 868 MHz Sigfox Monarch zones and uses an external antenna connection to deliver ultra-low-power bidirectional uplink/downlink communication on the Sigfox public 0G network. A Sigfox module is a pre-certified radio module that implements the proprietary Sigfox Low-Power Wide-Area Network (LPWAN) protocol stack, which sits above the physical sub-1 GHz layer (typically 868 MHz in Europe) and below the application firmware. Within the broader taxonomy, Sigfox belongs to LPWAN -> Low-Power Wide-Area Networking -> Wireless Connectivity -> RF & Wireless modules -> Semiconductor assemblies. By embedding the full Sigfox protocol stack and offering AT-command control, the WSSFM10R1AT lets product firmware treat the radio as a black-box modem rather than re-implementing the physical and MAC layers on a bare transceiver. Key features of the WSSFM10R1AT include: Sigfox RCZ1 zone compliance (ETSI EN 300 220), an integrated 31-pin SMD form factor, AT-command interface for UART-driven control, and an ultra-low-power sleep mode suited to coin-cell and battery-operated IoT endpoints. The module operates from a single 3.3 V supply typical of low-power IoT sensor nodes, and integrates the matching network, SAW filter, and crystal reference, simplifying host PCB design. Pin 1 marking and 31-pin SMD pad pattern enable surface-mount assembly on standard reflow profiles. The architecture combines a sub-1 GHz RF transceiver core with an on-board microcontroller running the Sigfox protocol stack. The host MCU communicates with the module over UART using AT commands, transparently handling Sigfox frame formation, sequence-number generation, and ETSI duty-cycle compliance. This offloads a significant firmware burden from the host, allowing the application processor to focus on sensing, local processing, and power management rather than radio protocol details. Typical applications include wireless battery field monitoring, smart parking sensors, asset tracking, environmental monitoring (temperature, humidity, air quality), smart agriculture soil/livestock sensors, and industrial IoT endpoints requiring multi-year battery operation. The RCZ1 zone targets Europe, the Middle East, and parts of Africa where Sigfox 868 MHz infrastructure is deployed. When designing with this module, observe the antenna placement guidelines from the manufacturer: keep the antenna radiating element clear of ground planes and battery metals, and route the host UART lines away from noisy switching power traces to avoid coupling into the receiver. Pay attention to host-side flow-control handshaking during long Sigfox frame transmissions.

WSSFM10R4AT - Sigfox RC4 RF Module, 1GHz, 31-Pin SMD | Wisol
The Wisol WSSFM10R4AT is a Sigfox-certified sub-1 GHz RF transceiver module designed for operation in the Sigfox RC4 (Regional Configuration 4) zone, which covers Latin America and parts of Asia-Pacific. Built around the S2-LP sub-1 GHz transceiver IC and an integrated STM32 microcontroller, the module delivers long-range, ultra-narrowband connectivity in a compact 13x20 mm surface-mount package with a 31-pin SMD land pattern, supplied on tape and reel for high-volume SMT assembly. A Sigfox RC4 RF module is a pre-certified radio module that operates on the 920-923 MHz band with Sigfox-defined duty-cycle and ETSI/FCC-style emission profiles. The module abstracts the radio PHY and regional regulatory requirements, allowing embedded developers to focus on application logic rather than RF design, antenna matching, or protocol certification. Sigfox modules sit within the broader category of low-power wide-area network (LPWAN) wireless modules, alongside LoRaWAN and NB-IoT modules, but offer a managed operator-supplied network service. Key features of the WSSFM10R4AT include Sigfox RC4 zone certification, an integrated S2-LP sub-1 GHz transceiver with ETSI EN 300 220 compliance, UART and SPI host interfaces, low-power standby modes suitable for battery-powered IoT deployments, and an onboard STM32 MCU for application-level firmware execution. The module supports the bidirectional Sigfox protocol and is pre-loaded with the Sigfox modem library. Typical applications include battery-powered IoT sensor nodes, asset tracking and fleet management devices, smart agriculture soil moisture and livestock monitors, smart city infrastructure (parking sensors, environmental monitors), industrial telemetry and remote meter reading, and wireless alarm systems. The 13x20 mm footprint is significantly smaller than the prior WSSFM10P module generation, enabling compact end-product designs. When designing with this module, ensure the host microcontroller issues AT commands (or runs the Sigfox modem library) over UART at the supported baud rates, and provide adequate clearance around the antenna area to preserve the Sigfox RC4 RF performance budget. Keep module supply voltage within the datasheet range and observe solder-profile recommendations for the 31-pin SMD land pattern during SMT assembly.
WSSFM11R2DAT - Sigfox RC2/RCZ4 Dual-Mode Sub-1GHz Module | WISOL
The WISOL WSSFM11R2DAT is a Sigfox-certified dual-mode RF transceiver module supporting RC2 and RCZ4 regional zones, housed in a 31-pad QFN-style surface-mount package measuring 13 mm x 20.2 mm x 1.1 mm. The module integrates a Sub-1GHz RF transceiver, embedded microcontroller, and matching network in a PBA (Printed Board Assembly) form factor that drops directly onto a host PCB. A Sigfox module is a pre-certified, ultra-narrowband (UNB) wireless connectivity module that allows IoT devices to transmit small messages (typically 12 bytes uplink, 8 bytes downlink) over the Sigfox global low-power wide-area network (LPWAN). Sigfox modules fit into the broader hierarchy of IoT connectivity modules: RF module > Sub-1GHz module > Sigfox module > LPWAN module > wireless module > IoT component. They are used when battery-powered devices must run for years on a single cell while sending periodic sensor data over licensed-and-free sub-GHz spectrum. Key features include dual-region RC2 (Americas/Asia) + RCZ4 (Japan/Korea compatible) coverage in a single hardware SKU, integrated antenna matching, low standby current for multi-year battery operation, and an SPI/UART host interface for microcontroller integration. The module requires only a 3.3 V supply, a few passives, and an antenna trace or chip antenna. Technically, the WSSFM11R2DAT is built around a dedicated Sigfox protocol stack firmware running on an embedded low-power MCU, paired with a Sub-1GHz RF front-end tuned for the 902–928 MHz (RC2) and 920–928 MHz (RCZ4) bands. This dual-mode approach lets one BOM serve devices shipped into multiple geographic markets, eliminating separate regional SKUs. Typical applications include battery-powered IoT asset trackers, smart-meter AMR (automatic meter reading) modules, environmental sensors, agricultural monitoring nodes, and industrial predictive-maintenance telemetry. When designing with this module, observe the Sigfox reference antenna layout from the datasheet and follow the host MCU's SPI timing for command sequencing; failure to honor timing margins causes join/provisioning failure on first power-up. This page synthesizes verified distributor pricing, drop-in Sigfox-module alternatives, and practical RF/antenna design notes beyond the manufacturer datasheet.
WVBP-283-WR28+ - 27.5-28.35 GHz WR28 Waveguide BPF | Mini-Circuits
The Mini-Circuits WVBP-283-WR28+ is a rectangular waveguide bandpass filter covering 27500-28350 MHz in the standard WR28 waveguide interface, jointly developed by Mini-Circuits and Virginia Diodes for millimeter-wave applications. Housed in a precision-machined TH2793-2 case style with high-quality plating, the filter delivers low insertion loss in the passband, outstanding return loss, and high stopband rejection with fast roll-off characteristics typical of metrology-grade construction. A waveguide bandpass filter is a passive RF component that passes a defined frequency window through a hollow metallic waveguide structure while rejecting energy outside that window. Unlike microstrip or lumped-element filters, waveguide BPFs use precisely machined resonant cavities that exhibit extremely low loss at millimeter-wave frequencies, making them the preferred topology above ~26 GHz where PCB-based filters become lossy and dispersive. The WVBP-283-WR28+ sits within the broader taxonomy of RF filters -> bandpass filters -> waveguide filters -> millimeter-wave components. Key features of this filter include its 27500-28350 MHz passband tailored for the 28 GHz 5G FR2 band, WR28 standard waveguide flange compatibility covering 26.5-40 GHz, and the rugged machined construction characteristic of the WVBP series. The WVBP family spans 27 to 86 GHz across multiple band splits, allowing system designers to standardize on a single filter family across millimeter-wave prototyping and production. The WVBP-283-WR28+ employs precision-machined cavity resonator topology rather than coupled-line or printed topologies, yielding Q factors that planar structures cannot achieve at these frequencies. The use of standard WR28 flange interfaces means the filter mates directly with any WR28 system without adapters, simplifying 5G FR2 and Ka-band test setups. Typical applications include 28 GHz 5G FR2 base-station filtering, Ka-band satellite-communication front-ends, automotive 28 GHz radar test setups, and millimeter-wave research instrumentation. The filter's narrow 850 MHz passband makes it well-suited to channelized 5G test beds and spurious-rejection in up/down-converter chains. When integrating this part, ensure the mating flange surfaces are clean and the bolts are torqued evenly to specified values to maintain return loss. The filter is non-hermetic; for outdoor deployments, add a weatherized radome or pressurized dry-air enclosure to prevent moisture-induced performance drift.

WVBP-583-WR15+ - 57.2-59.4 GHz WR15 Waveguide BPF | Mini-Circuits
The Mini-Circuits WVBP-583-WR15+ is a rectangular waveguide bandpass filter covering 57200 to 59400 MHz in the WR15 waveguide band, co-developed with Virginia Diodes for millimeter-wave and THz instrumentation. It delivers 0.7 to 1.5 dB passband insertion loss, 20 to 84 dB out-of-band rejection, and is built into Mini-Circuits case style TH2793-1 with an ENV80 environmental rating. The filter uses the standard WR15 rectangular waveguide interface (UG-387/U-M style flange) for drop-in compatibility with V-band millimeter-wave test setups. A waveguide bandpass filter is a passive frequency-selective component realized as a section of rectangular waveguide with precisely machined resonant irises or posts that reflect unwanted frequencies and transmit a defined passband. In the signal chain hierarchy, waveguide BPFs sit between the antenna/down-converter and the low-noise receiver front end, and they belong to the broader RF filter family which includes coaxial cavity, lumped LC, and dielectric resonator types. Waveguide implementations dominate above ~26 GHz because metallic rectangular waveguide has lower loss than coaxial interconnect at millimeter-wave frequencies. Key features of the WVBP-583-WR15+ include an operating temperature range of -40C to +85C, support for the WR15 standard waveguide band (50 to 75 GHz), and rejection skirts designed for adjacent-channel filtering in dense 5G/60 GHz, 802.15.3d, and E-band measurement scenarios. The ENV80 environmental rating indicates qualification for indoor controlled-environment lab use. The filter ships in Mini-Circuits' TH2793-1 machined aluminum housing with high-quality plating for stable electrical performance across temperature. Architecturally, the filter uses precision-machined resonant structures in a split-block waveguide cavity, leveraging Virginia Diodes' metrology-grade millimeter-wave manufacturing experience. This topology yields steep roll-off skirts and high rejection (>40 dB typical) at frequencies close to the passband edges, which is essential for rejecting LO leakage and image responses in heterodyne receivers. The mechanical tolerances are typically held to a few microns, which is critical at 60 GHz where the waveguide dimensions are on the order of 3.76 mm by 1.88 mm. Typical applications include 60 GHz WiGig / 802.11ay / 802.15.3d channel filtering, automotive 60 GHz radar pre-select filtering, millimeter-wave point-to-point backhaul link filtering, V-band radiometer and atmospheric measurement receivers, and VNA-based S-parameter measurements requiring harmonic or image rejection. The standard WR15 flange also makes it useful as a building block in custom millimeter-wave test fixtures and over-the-air measurement systems. When integrating the WVBP-583-WR15+, ensure flange torque and alignment follow standard precision waveguide practice to minimize RF leakage. Use UG-387/U-M compatible flanges and dowel pins when mating, and tighten to the manufacturer-specified torque to avoid passband ripple from flange misalignment. Add a calibrated through-line before any system calibration so the filter can be de-embedded if absolute amplitude accuracy is required. This page synthesizes distributor pricing, drop-in same-band alternatives, and design notes not found in the manufacturer datasheet, helping engineers quickly evaluate the WVBP-583-WR15+ for V-band and adjacent 60 GHz system designs.
WVBP-613-WR15+ - 57.2-65.9 GHz WR15 Waveguide BPF | Mini-Circuits
The Mini-Circuits WVBP-613-WR15+ is a rectangular waveguide bandpass filter covering 57.2 GHz to 65.9 GHz in the WR15 waveguide band, jointly developed by Mini-Circuits and Virginia Diodes for millimeter-wave and THz applications. Per the manufacturer datasheet, it delivers 0.4 to 1 dB insertion loss, 20 to 94 dB rejection, and operates over a -40C to +85C temperature range, all housed in a precision-machined TH2793-1 case style with standard WR15 flange interface. What is a waveguide bandpass filter? A waveguide bandpass filter is a passive RF component realized inside a hollow rectangular metallic waveguide that allows signals within a defined passband to propagate while rejecting frequencies outside that band. It sits hierarchically between a bandpass filter and a cavity/waveguide filter within the broader passive RF component taxonomy, and is the preferred topology above approximately 26 GHz where microstrip and lumped-LC structures become too lossy. WR15 designates the EIA-standard rectangular waveguide size for V-band (50-75 GHz), giving WVBP-series filters natural compatibility with V-band test equipment, automotive radar, and emerging 6G research hardware. Key features include precision machined tolerances and high-quality plating that deliver outstanding return loss and super-high rejection with fast roll-off near the band edges. The filter is offered with an environmental rating of ENV80 and is supported by Mini-Circuits application notes AN03-36 (measurement methods), AN40-005 (ESD prevention), and AN75-004 (band pass filters with linear phase response). The passband centered on the V-band unlicensed window makes the part attractive for short-range high-throughput links and instrumentation front-ends. Architecturally, the WVBP-613-WR15+ uses a multi-resonator iris-coupled waveguide cavity topology, which is what enables both the steep skirt selectivity and the wide spurious-free stopband quoted by Mini-Circuits. Because it is a passive waveguide structure with no active devices, no DC bias or quiescent current is required, simplifying system BOM and eliminating a noise-injection path common to active filter alternatives. Typical applications include V-band test and measurement instrumentation, automotive 60 GHz radar pre-selection, 5G/6G mmWave front-end filtering, and E-band-adjacent research platforms. Engineers commonly pair it with V-band mixers, LO multipliers, and downconverter modules in transceiver chains. When designing in the WVBP-613-WR15+, engineers must respect the WR15 flange alignment and torque requirements to prevent leakage that would degrade rejection. A 50-ohm transition to/from the waveguide is not needed at the flange interface itself, but the upstream/downstream probe or horn transition should be matched to minimize ripple in-band. This page synthesizes distributor pricing, drop-in alternatives drawn from the Mini-Circuits WVBP-series family, and practical design notes not found in the bare manufacturer datasheet, giving engineers an at-a-glance procurement and substitution reference.
WVBP-64-WR15+ - WR15 Waveguide BP Filter 59.4-61.6 GHz | Mini-Circuits
The Mini-Circuits WVBP-64-WR15+ is a rectangular waveguide bandpass filter covering 59.4 to 61.6 GHz in the WR15 (V-band) standard interface, co-developed with Virginia Diodes for millimeter-wave and THz metrology-grade applications. It delivers 0.8 to 1.5 dB typical insertion loss in the passband, 20 to 98 dB stopband rejection, and is supplied in precision-machined, plated TH2793-1 case style with environmental rating ENV80. A waveguide bandpass filter is a passive RF component that selects a narrow range of frequencies propagating in a hollow metallic waveguide while rejecting signals outside the passband. In the millimeter-wave hierarchy, waveguide BPFs sit alongside cavity filters, microstrip filters, and lumped-element filters; they are the preferred solution above ~26 GHz because waveguide offers lower loss than planar transmission lines and handles higher power than microstrip. WR15 is the EIA-standard rectangular waveguide for V-band (50-75 GHz), with inner dimensions of 3.76 mm x 1.88 mm and UG-385/U flange. Key features of the WVBP-64-WR15+ include a centered 60.5 GHz passband with sub-dB insertion loss, super-high rejection with fast roll-off (achieved through multi-resonator precision machining), and outstanding return loss matched to the WR15 waveguide impedance. The filter is designed for low-loss millimeter-wave signal chains where planar filters would add unacceptable insertion loss and microstrip filters would radiate. The case style TH2793-1 supports standard waveguide flanges, enabling drop-in assembly into V-band test setups. Technically, the WVBP-series leverages Virginia Diodes' metrology-grade machining and plating processes to achieve surface finish and dimensional tolerances that minimize passband insertion loss while maximizing out-of-band rejection. Multiple coupled resonator cavities produce the sharp roll-off characteristic, and the precision plating stabilizes performance across the -40 to +85 degree C operating range. Compared with absorptive or planar alternatives, the WVBP-series achieves cleaner passband edges suitable for aerospace and 6G research. Typical applications include V-band 60 GHz unlicensed wireless backhaul and 5G/6G research testbeds, 60 GHz WiGig (802.11ad/ay) coexistence filtering, automotive 77 GHz radar development hardware, satellite and earth-station uplink/downlink filtering, and millimeter-wave metrology instrumentation. The 59.4-61.6 GHz window overlaps the FCC unlicensed 60 GHz band and is the standard channel for emerging 6G sub-THz experimentation. When designing with this filter, account for the WR15 flange torque specification and ensure the mating flange surface is clean to maintain return loss. The filter is non-catalog / order-on-request with lead time measured in weeks; verify current availability through Mini-Circuits sales before committing to a production design.

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.
