FMSW6531

RF Switches Overview

The FMSW6531 is an SP4T coaxial switch manufactured by Fairview Microwave. It utilizes an electromechanical relay topology with latching functionality. The component supports a frequency range from DC to 18 GHz and features SMA connectors. It is rated for 90 Watts of power handling and operates on a 12 VDC coil voltage. The unit offers IP64 ingress protection and includes solder pin termination.

RF Switches Feature Summary

• SP4T topology with latching electromechanical relay operation
• High-frequency performance extending to 18 GHz
• IP64 rated environmental protection for the housing
• SMA connector interface with solder pin termination

RF Switches Applications

• RF signal routing in high-frequency test setups
• Antenna switching systems requiring latching states
• Telecommunications infrastructure signal distribution
• Aerospace and defense electronic warfare subsystems

RF Switches Procurement Notes

Verify the specific datasheet version for precise electrical tolerances and mechanical drawings before integration. Confirm that the 12VDC latching requirement aligns with the control circuit design. Ensure the IP64 rating meets the environmental exposure specifications of the intended installation site. Validate connector compatibility with existing SMA interfaces in the system architecture.

RF Switches Selection Notes

Select this model when a four-port switching solution is required up to 18 GHz. The latching feature reduces continuous power consumption compared to non-latching relays. Consider the 90W power rating against peak signal levels. The IP64 enclosure provides basic dust and water resistance for controlled environments.

RF Switches Part Context

This component belongs to the Fairview Microwave series of high-performance coaxial switches. It serves as a critical interconnect element in RF chains where signal path selection is necessary. The SP4T configuration allows connection between one common port and four selectable output ports.

RF Switches Replacement Considerations

Direct substitutes must match the SP4T topology, 18 GHz frequency limit, and SMA interface. Verify equivalent power handling and latching voltage requirements. Cross-reference mechanical dimensions for panel cutout compatibility.
