RF Circulators And Isolators Procurement Notes

Verify the specific suffix variant required, as the base model may correspond to different connector configurations or pinouts documented in official datasheets. Confirm RoHS compliance status and environmental classifications such as MSL levels before procurement. Ensure the selected unit matches the exact frequency and power specifications needed for the target application to avoid compatibility issues.

RF Circulators And Isolators Selection Notes

Select this component when a dual junction isolator is required for the 1.2 to 1.4 GHz band. Consider the 200 W power rating and 0.8 dB insertion loss against system requirements. Evaluate the SMA interface compatibility with existing circuitry. Compare physical dimensions against available board space. Review thermal limits to ensure operation within the specified temperature range.

RF Circulators And Isolators Part Context

The D4I0112 belongs to the DiTom Microwave series of RF isolators. It is part of a family that includes variants like D4I0112-1, D4I0112-2, and D4I0112-3, which may differ in connector gender or specific electrical tolerances. These components are generally used in high-frequency applications where signal integrity and directionality are critical. The series is characterized by coaxial construction and modular packaging.

RF Circulators And Isolators Replacement Considerations

Direct substitutes include other DiTom models within the D4I0112 series, such as D4I0112-1, D4I0112-2, or D4I0112-3, provided connector configurations match. Cross-manufacturer replacements must be verified for identical frequency range, power handling, and insertion loss characteristics. Always consult official documentation to confirm functional equivalence.
