RF Circulators And Isolators Procurement Notes

Verify RoHS compliance status and specific datasheet revisions before procurement. Confirm connector gender and physical dimensions match system requirements. Check manufacturer lead times as availability may vary. Ensure operating temperature ranges align with environmental conditions. Validate part number suffixes against official DiTom documentation.

RF Circulators And Isolators Selection Notes

Select this component when high isolation and moderate power handling are required in the 800-900 MHz band. Consider the dual junction architecture for superior performance compared to single junction variants. Evaluate physical space constraints due to the specific module dimensions. Compare insertion loss and VSWR metrics against system sensitivity requirements.

RF Circulators And Isolators Part Context

This model belongs to the D4I0890 series of coaxial isolators from DiTom Microwave. It shares the same frequency range and core technology as other series members but differs in connector configuration and internal junction structure. The series is categorized under RF circulators and isolators for wireless and communication applications.

RF Circulators And Isolators Replacement Considerations

D3I0890-2 offers similar frequency coverage but utilizes a single junction design with different physical dimensions.
