FMWCT1076

RF Directional Couplers Overview

The FMWCT1076 is a WR-90 waveguide crossguide coupler manufactured by Fairview Microwave. It operates within the frequency range of 8.2 GHz to 12.4 GHz and provides a nominal coupling factor of 20 dB. The component features an N female coupled port for signal extraction and includes a UG-39/U square cover flange. This design facilitates integration into microwave systems requiring precise signal sampling or power monitoring in the specified millimeter-wave band.

RF Directional Couplers Feature Summary

• Utilizes WR-90 waveguide structure for low-loss transmission
• Provides stable 20 dB coupling across the operational bandwidth
• Includes UG-39/U square cover flange for secure mounting

RF Directional Couplers Applications

• Microwave signal monitoring and sampling
• Power measurement systems
• Test and measurement instrumentation

RF Directional Couplers Procurement Notes

Verify that the required coupling tolerance and directivity specifications align with system requirements. Confirm that the N female connector interface matches existing test equipment or cabling infrastructure. Ensure the WR-90 waveguide dimensions are compatible with the host assembly. Review the datasheet for insertion loss and VSWR limits to guarantee signal integrity in the application.

RF Directional Couplers Selection Notes

Select this component when a fixed 20 dB coupling ratio is necessary within the 8.2 GHz to 12.4 GHz range. The WR-90 format is suitable for high-power applications where coaxial connectors might be limiting. Consider the physical size and weight constraints associated with waveguide components compared to planar alternatives. Verify compatibility with standard UG-39/U flanges for installation.
