RF Circulators And Isolators Procurement Notes

Verify component authenticity through authorized DiTom Microwave channels or certified distributors. Confirm that the specific unit matches the D4I1840-3 designation and includes relevant RoHS compliance documentation. Ensure storage conditions maintain integrity prior to installation, as ferrite components require protection from physical shock and moisture exposure during handling.

RF Circulators And Isolators Selection Notes

Select this model when a 18 dB isolation level and 5 W power rating are required within the 18-40 GHz band. The Type-K female interface dictates compatibility with existing system cabling. Evaluate thermal management requirements against the specified operating temperature limits to ensure stable performance under continuous load conditions without exceeding junction temperature thresholds.

RF Circulators And Isolators Part Context

This component belongs to the D4I1840 series of RF isolators produced by DiTom Microwave. The series covers the 18 GHz to 40 GHz spectrum, offering various connector configurations and power ratings. The D4I1840-3 specifically utilizes Type-K female connectors and a single-junction architecture, distinguishing it from multi-junction variants or different connector types within the same product family.

RF Circulators And Isolators Replacement Considerations

Direct substitutes within the same series include the D4I1840-1 and D4I1840-2. These alternatives share identical frequency ranges and core electrical characteristics but may differ in connector configuration or specific mechanical tolerances. Verify interface compatibility before substitution.
