RF Circulators And Isolators Procurement Notes

Verify the specific connector gender and configuration matches the design requirements before ordering. Confirm that the thermal environment supports the specified 20 W average forward power without exceeding temperature limits. Ensure the SMA female interface aligns with existing cable assemblies. Check for any project-specific compliance documentation beyond standard RoHS3 certification if required by the end application.

RF Circulators And Isolators Selection Notes

Select this component when a circulator is needed for the 3.7–4.2 GHz band with moderate power handling capabilities. Consider the 0.3 dB insertion loss impact on system gain budget. Evaluate the 23 dB isolation level against system interference requirements. Verify that the SMA female connector type is compatible with the intended interconnect hardware and PCB layout constraints.
