WVBP-783-WR12+ - 76-81 GHz WR12 Waveguide Bandpass Filter | Mini-Circuits
MPN: WVBP-783-WR12+ ✓ NakahandaWVBP-783-WR12+ Ulas
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.

Tipikal na mga Gamit
WVBP-783-WR12+ ay nararapat para sa 6 aplikasyons: E-band Point-to-Point Backhaul Filtering, Automotive 77 GHz Radar Test, Millimeter-Wave Instrumentation and VNA Test, 5G FR2+ Research and Test, Satellite Payload Pre-Select Filtering, Defense and Electronic Warfare Test.
E-band Point-to-Point Backhaul Filtering
The WVBP-783-WR12+ provides pre-select filtering for E-band (71-86 GHz) point-to-point backhaul links where the WVBP-783-WR12+'s 76-81 GHz passband overlaps the FCC-allocated 71-76 / 81-86 GHz duplex pairs plus the 76-81 GHz common-band tier. Its 0.6-1.5 dB insertion loss adds minimal link-budget penalty, and the 20-91 dB rejection suppresses adjacent-channel interference that would otherwise desensitize the LNA. The WR12 flange mates to standard UG-387/U-M hardware used in commercial E-band transceivers, enabling drop-in integration at the antenna feed or transceiver input.

Automotive 77 GHz Radar Test
The WVBP-783-WR12+ is well suited for 77 GHz automotive radar test benches where its passband covers the 76-81 GHz ISM and radar-allocated spectrum. The -40 to +85 C operating range matches automotive test-chamber thermal envelopes, and the high rejection (up to 91 dB) protects sensitive radar target simulators from out-of-band interference. The WVBP-783-WR12+'s WR12 interface pairs directly with 77 GHz radar modules and ETSI/FCC band-limited measurement setups, providing clean pre-selection before the spectrum analyzer or signal generator stages.

Millimeter-Wave Instrumentation and VNA Test
The WVBP-783-WR12+ serves as a precision pre-filter in millimeter-wave vector network analyzer (VNA) frequency-extension test setups. Its metrology-grade insertion loss and Virginia Diodes-derived resonator precision make it suitable for characterizing DUTs in the 76-81 GHz range. The TH2793 case style provides repeatable mechanical alignment critical for repeatable VNA calibrations, while ENV80 environmental rating allows deployment in production ATE without special enclosures.

5G FR2+ Research and Test
The WVBP-783-WR12+ enables filtering for 5G FR2+ research platforms operating in the upper millimeter-wave bands beyond 76 GHz. The 76-81 GHz passband aligns with several experimental 6G candidate bands and research allocations, and the high-rejection skirt protects receivers from adjacent 5G FR2-1 and WiGig signals. The WR12 flange simplifies integration with FR2 test antennas and down-conversion modules, while the Mini-Circuits datasheet provides full S-parameter graphs for system simulation.

Talaan ng Disenyo
Flange cleanliness is critical at 80 GHz: any dust, fingerprint, or scratch on the WR12 flange face will introduce measurable leakage loss. Use IPA and lint-free swabs before each mating, and torque UG-387/U-M flange screws to the manufacturer-specified value (typically 4-6 in-oz). A single dirty joint can add 0.5-2 dB of loss and create resonances that destroy measurement accuracy.
The WVBP-783-WR12+ must be mounted on a rigid, vibration-free test bench or chassis. At WR12 wavelengths (~3.1 mm), mechanical flex in the waveguide section between the filter and the DUT can shift S-parameter phase references. Use rigid waveguide sections or precision-machined spacer blocks, and avoid flexible waveguide sections immediately adjacent to the filter when characterizing passband flatness.
When verifying the WVBP-783-WR12+ passband with a VNA, perform a full 2-port calibration at the WR12 test ports immediately before measurement. The 76-81 GHz band is at the edge of typical frequency-extension coverage, and connector repeatability dominates measurement uncertainty. Use a calibration kit with known WR12 standards and re-calibrate after any mechanical disturbance.
