FMW42F012

Overview

The FMW42F012 is a WR-42 high-pass waveguide filter manufactured by Fairview Microwave. It features a passband ranging from 20 GHz to 26.7 GHz with a bandwidth of 6700 MHz. The component utilizes UG cover flanges for connection and supports a maximum continuous wave power of 100 W. Key electrical specifications include a maximum insertion loss of 0.3 dB and a minimum rejection of 50 dB at 17 GHz.

Feature Summary

• High-pass filtering capability within the K-band frequency range
• Robust construction designed for high-power RF applications
• Standardized WR-42 waveguide interface compatibility

Applications

• K-band radar systems
• Satellite communication ground stations
• Test and measurement instrumentation

Procurement Notes

Verify the specific revision level, such as REV 1A, against project requirements before procurement. Confirm that the operating environment remains within the specified power and frequency limits. Ensure proper waveguide alignment during installation to maintain signal integrity and prevent mechanical damage to the flange interfaces.

Selection Notes

Select this component when a high-pass response is required between 20 GHz and 26.7 GHz in a WR-42 system. Consider the 0.3 dB insertion loss and 50 dB rejection specs for link budget calculations. Ensure the application does not exceed the 100 W CW power rating to avoid thermal failure or arcing within the waveguide structure.

Part Context

This part belongs to the Fairview Microwave line of WR-42 waveguide components. It is categorized under RF filters and is designed for use in high-frequency microwave circuits. The product is distributed through authorized electronics suppliers and is intended for professional engineering applications requiring precise spectral filtering.

Replacement Considerations

Check for equivalent WR-42 high-pass filters from other manufacturers if supply constraints exist. Verify that any substitute matches the 20-26.7 GHz passband, 100 W power handling, and UG cover flange dimensions to ensure mechanical and electrical compatibility.
