FMW28F012

Overview

The FMW28F012 is a WR-28 highpass waveguide filter manufactured by Fairview Microwave, designed for operation within the 30 GHz to 40 GHz frequency range. Constructed from brass, this component features a passband starting at 30 GHz and extending to 40 GHz. It supports an input power capacity of 50 W while maintaining an insertion loss of 0.5 dB and providing 50 dB of rejection. The unit utilizes a UG cover flange configuration and is packaged individually in a bag.

Feature Summary

• Highpass filtering capability with a defined 30 GHz to 40 GHz passband
• Robust brass construction ensuring durability in RF environments
• Supports high input power handling up to 50 W
• Low insertion loss of 0.5 dB for efficient signal transmission

Applications

• Millimeter-wave communication systems requiring high-frequency signal conditioning
• Test and measurement equipment operating in the 30-40 GHz band
• Radar systems utilizing WR-28 waveguide interfaces
• Satellite ground station components needing high isolation

Procurement Notes

Verify the specific flange type and dimensional tolerances against your system requirements before ordering. Confirm that the WR-28 interface matches your existing waveguide infrastructure. Check for any specific surface finish or plating requirements if corrosion resistance is critical for your deployment environment. Ensure the 50 W power rating exceeds your maximum operational signal levels to prevent component damage.

Selection Notes

Select this component when a highpass response is required specifically between 30 GHz and 40 GHz. The WR-28 size dictates compatibility with standard rectangular waveguides of these dimensions. Consider the 0.5 dB insertion loss impact on overall system gain. The brass material offers good conductivity but may require appropriate environmental protection depending on the installation location.

Part Context

This part belongs to Fairview Microwave's line of WR-28 waveguide signal conditioning components. It complements other passive devices like couplers, circulators, and adapters in the same frequency band. The product series focuses on providing reliable interconnect solutions for millimeter-wave applications where low loss and high power handling are essential performance criteria.

Replacement Considerations

No public confirmed substitute part numbers are available for this specific model. Direct replacement requires matching the WR-28 waveguide size, 30-40 GHz passband, and UG cover flange configuration exactly.
