FMSW6497

RF Switches Overview

The FMSW6497 is an electromechanical latching switch manufactured by Fairview Microwave. It features N-type connectors and operates from DC to 12.4 GHz. The device supports a power rating of 160 Watts with a coil voltage of 28 V. Key electrical specifications include a VSWR of 1.3, insertion loss ranging from 0.2 to 0.7 dB, and isolation of 60 dB. It utilizes solder pin termination and offers a mechanical life of 2 million cycles.

RF Switches Feature Summary

• Electromechanical latching relay design for signal routing
• N-type connector interface supporting high power applications
• Self-cut off mechanism with integrated diodes

RF Switches Applications

• RF signal switching in test and measurement equipment
• Automated test systems requiring high power handling
• Telecommunications infrastructure signal routing

RF Switches Procurement Notes

Verify the specific coil voltage requirement, as sources indicate both 12V and 28V variants exist within the FMSW64xx series. Confirm that the 28V specification aligns with your system's power supply capabilities before ordering. Ensure the solder pin termination style matches your PCB layout constraints. Check regional availability restrictions as some distributors may limit sales in certain areas.

RF Switches Selection Notes

Select this component when a high-power RF switch with N-type interfaces is required up to 12.4 GHz. The latching nature reduces power consumption during state retention compared to non-latching relays. Consider the 160 Watt power rating for high-energy signal paths. Verify the 28V coil voltage against available control logic levels. Compare insertion loss and isolation specs against other SPDT switches if signal integrity is critical.

RF Switches Part Context

This part belongs to Fairview Microwave's line of coaxial switches. It serves as an alternative to solid-state switches where higher power handling and lower insertion loss are prioritized over switching speed. The N-type interface provides robustness for benchtop or rack-mounted applications compared to smaller SMA or BNC connectors.

RF Switches Replacement Considerations

The FMSW6491 is a similar SPDT electromechanical switch from the same manufacturer but operates at a lower frequency range (DC to 12.4 GHz vs potentially different specs) and uses a 12V coil voltage. Verify frequency coverage and coil voltage compatibility before substituting.
