RF Switches Procurement Notes

Verify the specific electrical parameters against the official Fairview Microwave datasheet before integration. Confirm that the required coil voltage (26-30 V) and current (90 mA) are compatible with your control circuitry. Ensure the application does not exceed the maximum supported power level of 90 W or the frequency limit of 18 GHz to maintain performance specifications.

RF Switches Selection Notes

Select this component when high-frequency switching up to 18 GHz is required alongside significant power handling capabilities. Consider the specific drive voltage requirements, as it differs from standard low-voltage relays. Evaluate the insertion loss characteristics against system sensitivity needs. Compare against other Fairview Microwave switches if broader frequency ranges or different form factors are necessary.
