WVBP-833-WR12+ 概要
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.

主な用途
WVBP-833-WR12+ の用途: 6 件s: E-band Point-to-Point Backhaul, Automotive Radar Prototyping (76-81 GHz), Millimeter-Wave Test & Measurement Instrumentation, 6G Research Testbeds and Terahertz Imaging Front-Ends, Satellite-Ground Uplink Down-converter Stages, Photonics-Modulated Millimeter-Wave Links.
E-band Point-to-Point Backhaul
The WVBP-833-WR12+ is well-matched to E-band point-to-point backhaul links operating in the 81-86 GHz light-licensed band, where its 0.5-1 dB insertion loss preserves link margin over multi-kilometer hops. In a typical link it sits between the diplexer and the E-band transceiver up/down-converter stage to suppress transmit LO leakage and image products before the radiating chain. Designers prefer a WR12 waveguide filter here because planar PCB filters at 80+ GHz show 5-10 dB more loss, eroding fade margin. The 20-90 dB rejection range protects the receiver from out-of-band interferers and is well-matched to the FSPL environment at 1-5 km path lengths.
おすすめ
Automotive Radar Prototyping (76-81 GHz)
For 76-81 GHz automotive radar prototyping, the WVBP-833-WR12+ provides the cleanest available bandpass shape in WR12 even though its passband starts at 81 GHz versus the 76 GHz edge of the automotive band. Inserting it as a preselector after the radar MMIC suppresses wideband noise and image responses in lab testbeds, where the 20-90 dB rejection is critical for dynamic-range sweeps. The 0.5-1 dB insertion loss adds less than the noise-figure penalty of a planar equivalent at 77 GHz. Designers should verify with a VNA sweep that the 81 GHz lower edge of the filter still passes their radar's upper IF or modulation bandwidth.
おすすめ
Millimeter-Wave Test & Measurement Instrumentation
In bench measurement setups the WVBP-833-WR12+ functions as an image-reject or harmonic-isolation filter ahead of spectrum analyzer converters and noise-figure meters in the E-band. Its precision-machined split-block housing, ENV80 environmental rating, and -40 to +85 °C operating range mean it survives lab and chamber cycling without retuning. Compared with a YIG-tuned or coaxial filter, the waveguide implementation offers 20-90 dB rejection at less than 1 dB insertion loss, substantially improving measurement floor. The TH2793 case style is small enough to fit modular WR12 test fixtures alongside the DUT.
おすすめ
6G Research Testbeds and Terahertz Imaging Front-Ends
Universities and 6G research labs frequently use E-band filters like the WVBP-833-WR12+ to isolate sub-bands inside the 81-86 GHz research allocation. The WR12 flange mates directly to standard horn antennas and corrugated feeds used in propagation and channel-sounding campaigns. With 0.5-1 dB insertion loss, the filter does not noticeably degrade SNR in fast-Fourier channel measurements, and the 20-90 dB rejection rejects adjacent-channel interference in dense sub-band multiplexing. Virginia Diodes heritage also makes the part suitable for terahertz imaging front-ends where phase linearity is critical.
おすすめ
Satellite-Ground Uplink Down-converter Stages
Satellite-ground ground-station receive chains covering the E-band downlink use the WVBP-833-WR12+ as a preselector to suppress terrestrial 5G and adjacent satellite signals from bleeding into the LNA input. The 0.5-1 dB passband loss adds minimally to the cascade noise figure, while 20-90 dB rejection protects the LNA from saturation by out-of-band interferers. The split-block construction is rugged enough for fixed ground-station installations including outdoor radomes. Compared with a coaxial cavity filter at the same band, the waveguide version offers better unloaded-Q and lower loss.
おすすめ
Photonics-Modulated Millimeter-Wave Links
Photonics-assisted millimeter-wave links operating in the 81-86 GHz research window benefit from the WVBP-833-WR12+ as a photonic-to-electrical band-limiting filter. After a UTC-PD or traveling-wave photodetector, broadband optical upconversion produces mixing spurs that the filter suppresses by 20-90 dB outside the desired RF passband. The 0.5-1 dB insertion loss adds little to the optical-RF link budget, and the WR12 flange interfaces directly to photonic-mixer housings used in THz spectrometers. Designers should pair the filter with a photodetector bandwidth mask to optimize filter-photonic co-design.

主な差別化要因
- Cover the 81-86 GHz E-band without resorting to lossy planar filters （vs Planar microstrip / stripline BPF at the same band)
- Full-band 20-90 dB rejection protects the LNA in receive chains （vs Coaxial cavity filters at similar band)
- Drop-in fit with the WVBP-series WR12 family from the same manufacturer （vs Cross-brand WR12 BPF from Virginia Diodes / Filtronic)
設計ノート
Ensure the mating WR12/UG-387/U flange has a flatness of 0.0005 inch or better to prevent RF leakage and passive intermodulation at the E-band 81-86 GHz frequencies. Use the recommended torque on the four bolts (typically 4-6 in-lb) and a stainless-steel or beryllium-copper gasket for repeatable contact. Cleaning the flange with isopropanol before assembly is critical because a single fingerprint can introduce a measurable S21 bump in this band.
Mating the WVBP-833-WR12+ to a non-WR12 flange (for example WR15 or WR10 hardware) is a common error that mechanically fits imperfectly and produces a frequency shift. Always verify the case-style TH2793 outline against your block drawing before fixture fabrication. Note that the + suffix denotes RoHS compliance - the base WVBP-833-WR12 part is electrically identical but is not RoHS-compliant and must not be used in EU-restricted designs.
Operating temperature is -40 to +85 °C per ENV80, which is adequate for outdoor and lab environments but may be marginal for engine-bay or uncooled outdoor radome applications. For sustained operation near +85 °C the passband may drift by a few MHz due to thermal expansion of the housing; consult the datasheet for a measured thermal tuning curve. Add a thermal pad or chassis-mount heat spreader where the filter dissipates several hundred milliwatts of RF power in transmit chains.
コンプライアンス情報
RoHS compliance indicated by the plus (+) suffix per Mini-Circuits part-number convention; the base WVBP-833-WR12 (no plus) is non-RoHS. REACH status for the + variant is compliant per Mini-Circuits product page; halogen-free and conflict-minerals declarations are not explicitly published and marked unknown.
