RF Switches Procurement Notes

Verify the specific connector interface and termination style against your system requirements before ordering. Confirm that the 28 VDC coil voltage aligns with your control logic capabilities. Ensure the 40 GHz frequency range meets your application's upper limit needs. Check the 80 W power rating for compatibility with your signal levels. Validate the solder pin termination method matches your PCB layout constraints.

RF Switches Selection Notes

Select this component when broad bandwidth up to 40 GHz is required alongside high power handling capabilities. Consider the latching feature if power conservation during idle states is critical. Evaluate the 50 dB isolation specification against your system's leakage tolerance. Compare the 0.8 dB insertion loss impact on overall system gain. Assess the mechanical cycle life against expected switching frequencies.
