RF Circulators And Isolators Procurement Notes

Verify the specific port configuration against the official datasheet before ordering, as suffixes may alter connector types or pinouts. Confirm RoHS compliance status and export classification codes such as ECCN EAR99 for regulatory adherence. Ensure thermal management aligns with the specified operating temperature range during integration.

RF Circulators And Isolators Selection Notes

Select this component when a four-port directional flow is required between 1.7 GHz and 2.2 GHz. Consider the physical module size and SMA connector compatibility with existing PCB layouts. Evaluate the 150 W power rating against peak system loads to ensure reliability under continuous operation conditions.

RF Circulators And Isolators Part Context

This model belongs to the D4C1722 series of RF circulators from DiTom Microwave. Variants within this family share similar electrical specifications but differ in connector configurations and port arrangements. The D4C1722S-2 specifically denotes a four-port unit with mixed SMA connector polarities.

RF Circulators And Isolators Replacement Considerations

Direct substitutes include models like D4C1722S-1 or D4C1722S-5, provided they match the required port count and connector types. Verify that alternative part numbers maintain identical frequency ranges and power ratings to ensure functional equivalence in the circuit design.
