RF Switches Procurement Notes

Verify the specific datasheet version for the FMSW6359 to confirm exact electrical tolerances and mechanical dimensions. Ensure the host system provides the required 26-30 Vdc coil voltage. Confirm that the 50 Ohm impedance matches the system design requirements before integration.

RF Switches Selection Notes

Select this component when high-power handling up to 90 W is required at frequencies extending to 18 GHz. The latching feature reduces continuous power consumption compared to non-latching relays. Verify compatibility with SMA connector types and ensure adequate thermal management for the specified power levels.
