FMCP1157

RF Directional Couplers Overview

The FMCP1157 is an SMA 180-degree hybrid coupler manufactured by Fairview Microwave. It operates within a frequency range of 2 GHz to 8 GHz and provides a coupling factor of 3 dB. The component is rated for an average power handling capacity of 30 Watts, with a peak power rating of 300 Watts. This RF directional coupler module is designed for general-purpose applications requiring precise signal splitting or combining within the specified microwave frequency band.

RF Directional Couplers Feature Summary

• Provides 180-degree phase separation between output ports
• Maintains consistent 3 dB coupling across the operational bandwidth
• Supports high peak power handling up to 300 Watts

RF Directional Couplers Applications

• General-purpose RF signal distribution systems
• Balanced mixer local oscillator feed networks
• Push-pull amplifier drive stage configurations

RF Directional Couplers Procurement Notes

Verify the specific datasheet version from Fairview Microwave to confirm current electrical tolerances and mechanical dimensions. Ensure that system requirements align with the 30 Watt average power limit and 2-8 GHz frequency range before procurement. Confirm connector compatibility and mounting requirements for integration into existing test setups.

RF Directional Couplers Selection Notes

Select this component when a broadband 3 dB hybrid coupler is required for frequencies between 2 GHz and 8 GHz. Consider the 30 Watt average power rating for thermal management in high-power applications. Verify that the SMA interface matches the system cabling infrastructure and that the physical size fits within the available enclosure space.

RF Directional Couplers Part Context

This device belongs to the Fairview Microwave RF directional coupler product line. It serves as a passive microwave component used for signal monitoring, splitting, and combining. The hybrid coupler topology distinguishes it from standard directional couplers by providing specific phase relationships between its ports.

RF Directional Couplers Replacement Considerations

No public substitute part numbers are documented. Evaluate other SMA hybrid couplers from different manufacturers only if they match the 2-8 GHz frequency range, 3 dB coupling, and 30 Watt power ratings.
