RF Switches Procurement Notes

Verify the specific datasheet version provided by Fairview Microwave or authorized distributors to confirm exact electrical tolerances and mechanical dimensions. Ensure that the 28 V coil voltage requirement aligns with the control circuit design. Confirm that the solder terminal termination style matches the PCB layout or wiring harness specifications. Validate that the 90 W power rating exceeds the maximum expected signal power in the application to prevent component damage.

RF Switches Selection Notes

Select this component when high-frequency switching up to 18 GHz is required alongside significant power handling capabilities. The failsafe SPDT configuration ensures defined output states during power loss. Compare insertion loss and VSWR values against system sensitivity requirements. Ensure the physical form factor and solder terminal type are compatible with the assembly process. Consider thermal management needs given the 90 W power rating.
