BB202,115 - 6V Varactor Diode, SOD-523 | NXP | RF Tuning
The NXP Semiconductors BB202,115 is a low-voltage variable capacitance diode (varactor) fabricated in planar technology, housed in the ultra-small SOD-523 (SC-79) surface-mount plastic package, with a peak reverse voltage of 6 V and a capacitance ratio of 2.5 (condition C0.2/C2.3). It is designed as a single varactor for voltage-controlled tuning where supply rails are limited. A varactor diode, also called a varicap or variable capacitance diode, is a PN-junction diode operated in reverse bias so that its junction capacitance varies predictably with the applied reverse voltage. Within the semiconductor hierarchy it belongs to the RF discrete components family, alongside PIN diodes and Schottky diodes, and serves as the tuning element in voltage-controlled oscillators (VCOs), RF filters, and FM radio tuning circuits. Key features of the BB202 include its very low series resistance, which directly improves Q factor and phase-noise performance in oscillator tanks, and its low operating voltage requirement, which makes it compatible with battery-powered and low-voltage analog designs. The planar fabrication process yields tight capacitance tolerances and repeatable capacitance-voltage characteristics across production lots. The SOD-523 package has a footprint of approximately 1.2 mm x 0.6 mm, enabling very dense RF layouts and automated high-volume assembly. Technically, the reverse-bias junction capacitance decreases as reverse voltage increases; the stated capacitance ratio of 2.5 between 0.2 V and 2.3 V bias gives designers a usable tuning range without exceeding the 6 V peak reverse rating. Low series resistance minimizes tank losses, so loaded Q remains high, which matters directly for VCO phase noise and channel-select filter insertion loss. Typical applications include VCO tuning in RF transceivers, FM/AM radio tuning front ends, voltage-controlled LC filters, antenna-tuning networks, and tunable matching circuits in portable wireless devices. Its low bias voltage range suits handheld, battery-operated consumer electronics where only a 2-3 V tuning rail is available. A key design consideration is that tuning voltage must never drive the diode into forward conduction or beyond 6 V reverse bias; otherwise capacitance control is lost or the device is overstressed. Keep the tuning network's feed resistors high enough to preserve Q.

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.

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.

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.
