WVBP-283-WR28+ 概述
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.

典型应用
WVBP-283-WR28+ 适用于 6 应用s: 28 GHz 5G FR2 Base Station Filtering, Ka-Band Satellite Communication Front-End, Automotive 28 GHz Radar Test & Measurement, Millimeter-Wave Research Instrumentation, Point-to-Point 28 GHz Backhaul Links, mm-Wave EMC and Pre-Compliance Test.
28 GHz 5G FR2 Base Station Filtering
The WVBP-283-WR28+'s 27.5-28.35 GHz passband is aligned directly with the 3GPP n257 5G FR2 channel allocation, making it ideal for filtering the 28 GHz band in 5G base-station front-ends. Its WR28 waveguide interface integrates cleanly with Ka-band antenna feeds and up/down-converter modules without adapters. Compared with printed microstrip BPFs at 28 GHz (which typically exhibit 3-5 dB insertion loss), the WVBP-283-WR28+ machined-cavity topology delivers substantially lower passband loss, preserving link budget in the mm-wave transceiver chain. Placed between the antenna feed horn and the LNA/down-converter mixer, it suppresses out-of-band interference from adjacent 5G channels and unlicensed 24 GHz automotive radar.
推荐
Ka-Band Satellite Communication Front-End
The WVBP-283-WR28+ provides channel selectivity in Ka-band satellite-communication ground terminals and airborne satcom links operating near 28 GHz. Its low passband insertion loss and high stopband rejection translate directly into improved G/T and EIRP for the terminal, which are critical figures of merit in satellite link budget analysis. Deployed between the LNA and the down-converter mixer, it rejects image frequencies and adjacent satellite transponders. The rugged machined construction tolerates vibration and thermal cycling in mobile and airborne installations, while the standardized WR28 flange mates with industry-standard Ka-band LNAs, BPFs, and waveguide runs.
推荐
Automotive 28 GHz Radar Test & Measurement
Although production automotive radar primarily operates at 24 and 77 GHz, the WVBP-283-WR28+ supports 28 GHz prototype work for next-generation short-range automotive radar sensors and V2X research platforms. Its narrow 850 MHz passband enables precise spectrum analysis of chirp linearity and phase noise in 28 GHz radar prototypes, while the WR28 flange simplifies bench-test integration with vector network analyzers and spectrum analyzers equipped with WR28 test ports. Placed inline at the analyzer input, it isolates the device-under-test from analyzer image responses. The filter's machined-cavity topology provides the dynamic range required to characterize low-noise 28 GHz radar front-ends.
推荐
Millimeter-Wave Research Instrumentation
The WVBP-283-WR28+ serves as a channel-selection filter in millimeter-wave research instrumentation including 28 GHz channel-sounding testbeds, 6G exploratory test platforms, and university mm-wave propagation measurement campaigns. Its stable machined-cavity response provides the repeatable filtering required for reproducible channel measurements and over-the-air compliance testing. Connected between the 28 GHz signal source and the DUT or antenna, it removes harmonic content and source broadband noise. The ENV80 environmental rating and precision-machined construction ensure measurement stability across laboratory temperature cycles from 18 C to 28 C.
推荐
Point-to-Point 28 GHz Backhaul Links
The WVBP-283-WR28+ provides channelization and spurious rejection in 28 GHz point-to-point backhaul links used for urban 5G small-cell backhaul and enterprise mm-wave bridges. Its narrow passband aligns with licensed 28 GHz LMDS and 5G fixed-wireless access channels, enabling co-channel interference rejection in dense urban deployments. Deployed in the outdoor unit between the transceiver module and the feed horn, it protects the receiver from out-of-band interference. The filter's machined-cavity topology tolerates outdoor temperature swings and humidity better than printed BPFs, though a weatherized radome is recommended for unprotected rooftop installations.
推荐
mm-Wave EMC and Pre-Compliance Test
The WVBP-283-WR28+ functions as a preselector in EMC and pre-compliance test setups targeting unintentional radiators in the 28 GHz band. Its sharp roll-off rejects broadband noise from spectrum analyzer front-ends, improving sensitivity when measuring low-level 28 GHz emissions from prototype wireless devices. Connected to the input of a spectrum analyzer or test receiver with a WR28 test-port adapter, it enables quasi-peak and peak detector measurements per FCC and ETSI radiated-emission standards above 26.5 GHz. The filter's metrology-grade construction - originally developed by Virginia Diodes for measurement-grade equipment - provides the stability needed for repeatable compliance test results.

设计说明
Mating flange surfaces must be clean, flat, and free of burrs before bolting the WVBP-283-WR28+ into a waveguide run. Torque the 4-40 flange bolts evenly in a cross pattern to the manufacturer's specified value (typically 1.5-2.0 in-lb for WR28 UG-599/U flanges). Uneven torque causes flange gap and degrades return loss by 5-10 dB at 28 GHz. Use a precision waveguide torque driver for repeatable results in production test setups.
Do not rotate or twist the filter body relative to the mating flanges during bolt tightening - this induces mechanical stress and detunes the cavity resonators. Always bring the filter to its final orientation before making the flange connection. Misalignment greater than 0.05 mm at the flange interface can shift the passband center by 50-100 MHz at 28 GHz and reduce stopband rejection.
The WVBP-283-WR28+ is rated ENV80 per Mini-Circuits documentation but is not hermetically sealed. For outdoor or condensing-environment deployments, install a weatherized radome or pressurize the waveguide run with dry air at 0.5-1.0 psi to prevent moisture ingress. Moisture inside the cavity detunes the filter and can cause corrosion of the plating, permanently degrading Q and insertion loss.
For S-parameter characterization, calibrate the vector network analyzer at the test-port reference plane before connecting the WVBP-283-WR28+. Use a waveguide calibration kit (e.g., WR28 TRL or SOLT) for accurate measurements above 26.5 GHz. Coaxial calibration kits introduce ~1 dB of measurement uncertainty at WR28 frequencies due to the coax-to-waveguide transition. Estimated: typical VNA measurement uncertainty without waveguide cal is 1.5-2.0 dB at 28 GHz.
