FMWAT1023-20

Attenuators Overview

The FMWAT1023-20 is a WR-90 waveguide fixed attenuator manufactured by Fairview Microwave. It provides a nominal attenuation of 20 dB within the operating frequency range of 8.2 to 12.4 GHz. The component is designed for high-power applications, supporting an average power handling capacity of 2 W. It utilizes a standard WR-90 rectangular waveguide interface for seamless integration into microwave transmission systems requiring precise signal reduction without impedance mismatch.

Attenuators Feature Summary

• Fixed 20 dB attenuation value
• WR-90 waveguide interface compatibility
• Operational frequency range from 8.2 to 12.4 GHz
• 2 W average power handling capability

Attenuators Applications

• Microwave test and measurement setups
• Signal level adjustment in radar systems
• Attenuation requirements in communication links

Attenuators Procurement Notes

Verify the specific model suffix and physical dimensions against the official Fairview Microwave datasheet before procurement. Ensure that the WR-90 waveguide flange type matches the existing system infrastructure. Confirm that the 2 W average power rating is sufficient for the intended application environment to prevent thermal damage or performance degradation during operation.

Attenuators Selection Notes

Select this component when a fixed 20 dB reduction is required in the X-band frequency spectrum. The WR-90 form factor dictates compatibility with standard waveguide components. Consider the 2 W power limit when designing the system; if higher power handling is needed, alternative attenuator models must be evaluated. Ensure the frequency range covers the entire operational bandwidth of the signal source.

Attenuators Part Context

This part belongs to the FMWAT1023 series of waveguide attenuators from Fairview Microwave. The series includes variants with different attenuation values, such as 10 dB and 30 dB, all sharing the same WR-90 waveguide interface and frequency range. This specific model represents the mid-range attenuation option within the product line.

Attenuators Replacement Considerations

Direct substitutes include other manufacturers' WR-90 waveguide attenuators with 20 dB nominal attenuation and compatible flange standards. Verify that replacement units meet the 8.2 to 12.4 GHz frequency range and 2 W power handling specifications to ensure functional equivalence.
