RF Circulators And Isolators Procurement Notes

Verify that the specific part number matches the required space-grade qualification standards. Confirm connector gender compatibility, as this model includes both SMA female and SMA male ports. Ensure environmental ratings meet project thermal requirements, specifically the +65°C maximum operating limit. Check for RoHS compliance documentation if required by supply chain regulations.

RF Circulators And Isolators Selection Notes

Select this component when a space-qualified isolator is required for frequencies between 17.3 GHz and 22 GHz. Consider the mixed SMA connector types for interface flexibility in assembly. Evaluate the 10 W power handling against system peak power levels. The low VSWR of 1.25:1 ensures minimal signal reflection in sensitive RF paths.

RF Circulators And Isolators Part Context

This isolator belongs to DiTom Microwave's series of RF circulators and isolators intended for demanding environments. It shares design characteristics with other models in the DSI1722 family, such as the DSI1722-2 and DSI1722-3, which may offer different frequency ranges or connector configurations while maintaining similar structural robustness.
