RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and datasheet revision prior to ordering, as manufacturer part numbers may contain subtle suffix variations affecting interface types. Confirm RoHS compliance status and environmental testing requirements against project specifications. Ensure that the procurement channel provides valid traceability documentation for aerospace or defense applications. Cross-reference the exact model number with official DiTom Microwave documentation to avoid confusion with similar series components.

RF Circulators And Isolators Selection Notes

Select this component when operating frequencies strictly fall between 18 GHz and 26.5 GHz. Choose based on the requirement for Type-K female interfaces and 10 W power handling. Consider the physical dimensions of 1x0.5x0.7 inches for board space constraints. Evaluate the 1.6 dB insertion loss and 1.4 VSWR against system link budget requirements. Ensure the operating environment stays within the specified -20°C to +65°C range.
