FMSW6474

RF Switches Overview

The FMSW6474 is an SP4T electromechanical relay latching switch manufactured by Fairview Microwave. It operates from DC to 26.5 GHz with a 50 Ohm impedance. The device supports 90W power handling and utilizes a 28V coil voltage. It features SMA connectors, solder terminals, and indicator lights. The switch offers 1.1 VSWR, 0.2 dB insertion loss, and 80 dB isolation. It has a rated lifespan of 5 million life cycles.

RF Switches Feature Summary

• SP4T configuration with self-cut-off functionality for reliable signal routing
• Latching mechanism requiring only momentary power to maintain state
• Integrated indicators for visual status monitoring
• High-frequency performance up to 26.5 GHz

RF Switches Applications

• RF test and measurement equipment
• Telecommunications infrastructure switching
• Aerospace and defense radar systems
• Automated production testing environments

RF Switches Procurement Notes

Verify the specific connector polarity and terminal type against the official datasheet before integration. Confirm that the 28V control voltage aligns with existing system power supplies. Ensure the SMA interface matches the PCB or cable assembly requirements. Check the mechanical dimensions for panel cutout compatibility. Validate the 90W power rating against peak signal levels in the intended application path.

RF Switches Selection Notes

Select this component when high-frequency switching up to 26.5 GHz is required with low insertion loss. The latching feature reduces power consumption compared to non-latching alternatives. Consider the 5 million cycle lifespan for long-term reliability needs. The IP64 rating suggests suitability for controlled industrial environments. Verify that the self-cut-off function meets safety requirements for the specific RF path.
