FMWCP1086S-20

RF Directional Couplers Overview

The FMWCP1086S-20 is a general-purpose RF directional coupler manufactured by Fairview Microwave. It operates within a frequency range of 13.75 GHz to 14.5 GHz and provides a nominal coupling level of 20 ± 0.7 dB. The component utilizes a WR-62 waveguide interface for the main signal path, ensuring compatibility with standard rectangular waveguide systems in this band. A key design feature is the integration of an SMA female connector on the coupled port, facilitating direct connection to test equipment or downstream circuitry without additional adapters. This configuration supports precise signal monitoring and power measurement applications in microwave systems.

RF Directional Couplers Feature Summary

• Integrates an SMA female connector directly on the coupled port for simplified system interconnects
• Utilizes WR-62 waveguide interface to maintain structural integrity and performance at high frequencies
• Provides stable coupling characteristics suitable for general-purpose signal monitoring tasks

RF Directional Couplers Applications

• Microwave signal monitoring and sampling
• Power measurement setups requiring isolated coupled signals
• Test and measurement instrumentation interfaces

RF Directional Couplers Procurement Notes

Verify that the receiving infrastructure supports WR-62 waveguide dimensions and SMA female connectors. Confirm that the operational frequency range aligns with the 13.75 GHz to 14.5 GHz specification. Ensure that the required coupling tolerance of ± 0.7 dB meets the system's accuracy requirements. Check for any specific flange standards or mating hardware needs associated with the waveguide interface.

RF Directional Couplers Selection Notes

Select this component when a fixed 20 dB coupling value is required within the 13.75–14.5 GHz band. The integrated SMA connector simplifies design by eliminating the need for separate waveguide-to-coaxial transitions on the coupled port. Consider waveguide size constraints and ensure the system can accommodate the physical dimensions of the WR-62 crossguide structure.

RF Directional Couplers Part Context

This part belongs to Fairview Microwave's portfolio of RF directional couplers designed for microwave frequencies. It represents a specialized solution for applications where standard coaxial components cannot operate effectively due to frequency limitations. The use of waveguide technology allows for lower insertion loss and higher power handling compared to equivalent coaxial designs in this frequency range.

RF Directional Couplers Replacement Considerations

Direct substitutes must match the WR-62 waveguide interface and SMA female coupled port configuration. Verify that alternative models provide identical coupling values within the 13.75–14.5 GHz range. Cross-reference mechanical drawings to ensure flange compatibility and mounting requirements are met.
