FMWAT1008-3

Overview

The FMWAT1008-3 is a fixed waveguide attenuator manufactured by Fairview Microwave. It operates within the WR-22 waveguide band, covering a frequency range of 33 GHz to 50 GHz. The component provides a fixed attenuation value of 3 dB. It features a UG-383/U flange interface for secure mechanical connection. The device is rated for an average power handling capacity of 4 W. This unit is designed for integration into high-frequency microwave systems requiring precise signal reduction.

Feature Summary

• Provides fixed 3 dB attenuation in the WR-22 waveguide band
• Operates across the 33 GHz to 50 GHz frequency spectrum
• Utilizes UG-383/U round cover flange for standard waveguide interfacing
• Rated for 4 W average power handling capability

Applications

• Microwave test and measurement setups
• Signal conditioning in radar systems
• Satellite communication ground stations
• High-frequency laboratory equipment

Procurement Notes

Verify the specific model suffix and flange type against system requirements before ordering. Confirm that the WR-22 dimensions align with existing waveguide infrastructure. Ensure the 4 W average power rating meets the operational load. Check for availability constraints as this may be a specialized component. Validate the 33-50 GHz frequency coverage matches the application bandwidth needs.

Selection Notes

Select this component when a fixed 3 dB reduction is required in the Ka-band range. Ensure compatibility with WR-22 waveguide standards. Verify that the UG-383/U flange matches the mating hardware. Consider the 4 W power limit for thermal management. Compare against variable attenuators if adjustable loss is needed instead.

Part Context

This part belongs to Fairview Microwave's waveguide attenuator series. It complements other fixed and variable attenuators in the FMWAT product line. The WR-22 designation indicates its specific waveguide size for high-frequency operation. It serves as a passive component for signal level adjustment in microwave circuits.

Replacement Considerations

Direct substitutes must match the WR-22 waveguide size, 33-50 GHz frequency range, 3 dB attenuation, and UG-383/U flange interface. Verify power handling ratings are equal or higher. Cross-reference with other manufacturers offering WR-22 fixed attenuators.
