RF Switches Procurement Notes

Verify the specific failsafe state configuration (normally open or normally closed) against system requirements before procurement. Confirm that the TTL control voltage levels match the driving circuitry specifications. Ensure the SMA connector gender and flange type align with existing cable assemblies. Validate that the 90W power rating exceeds the maximum expected signal power in the application path to prevent component damage during operation.

RF Switches Selection Notes

Select this model when a failsafe mechanism is critical for system safety or data integrity during power loss. Compare the 18 GHz frequency limit against the highest operational harmonic content of the signal chain. Evaluate the physical footprint and mounting requirements against available chassis space. Consider the thermal dissipation needs associated with 90W power handling in enclosed environments compared to solid-state alternatives.

RF Switches Part Context

This component belongs to Fairview Microwave's series of high-performance electromechanical switches. It complements their portfolio of coaxial switches and amplifiers by offering robust mechanical switching capabilities for high-power signals where solid-state devices may lack sufficient linearity or power handling capacity.

RF Switches Replacement Considerations
