FMWCT1022

RF Directional Couplers Overview

The FMWCT1022 is a WR-90 waveguide crossguide directional coupler manufactured by Fairview Microwave. It operates within the frequency range of 8.2 GHz to 12.4 GHz, covering the standard X-band spectrum. The component provides a nominal coupling level of 40 dB, ensuring precise signal sampling for measurement applications. It features a module construction with a UG-39/U square cover flange configuration for secure mounting and integration into waveguide systems.

RF Directional Couplers Feature Summary

• Utilizes WR-90 waveguide geometry for high-frequency performance
• Provides stable 40 dB nominal coupling across the operational band
• Incorporates UG-39/U square cover flange for standardized mounting

RF Directional Couplers Applications

• Signal monitoring in radar systems
• Power measurement setups in microwave test equipment
• Feedback loop coupling in communication transmitters

RF Directional Couplers Procurement Notes

Verify the specific flange type and coupling tolerance requirements against the official datasheet before ordering. Confirm that the WR-90 dimensions align with your existing waveguide infrastructure. Ensure the operating frequency range of 8.2 GHz to 12.4 GHz meets your system specifications. Check for any required accessories such as mating flanges or mounting hardware not included in the base unit.

RF Directional Couplers Selection Notes

Select this component when a fixed 40 dB coupling factor is required in the X-band range. The WR-90 size dictates the physical constraints of the installation. Consider the power handling capabilities if used in high-power transmission lines. Verify that the module form factor fits within the available space of the equipment chassis or waveguide run.

RF Directional Couplers Part Context

This part belongs to Fairview Microwave's catalog of RF and microwave components. It serves as a passive device for signal distribution and measurement. The product is categorized under waveguide couplers, distinct from coaxial or connector-only items. It supports engineering tasks requiring non-intrusive signal tapping in high-frequency environments.

RF Directional Couplers Replacement Considerations

No public substitute part numbers are documented. Cross-reference only with other WR-90 40 dB couplers if availability is an issue. Ensure identical flange configurations and frequency ranges when evaluating alternatives.
