RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation against official DiTom Microwave documentation to confirm exact electrical tolerances and connector configurations. Ensure that the procurement channel provides valid traceability for RoHS3 compliance status. Cross-reference the part number with current manufacturer datasheets to validate availability and lead times prior to order placement.

RF Circulators And Isolators Selection Notes

Select this component when a circulator is required for the 3.7–4.2 GHz band with SMA interfaces. Consider the 20 W power handling limit and 23 dB isolation requirement relative to system design constraints. Evaluate the VSWR of 1.15 for impedance matching needs. Confirm mechanical module dimensions fit the target assembly space.

RF Circulators And Isolators Part Context

This model belongs to the D4C3742 series of RF circulators produced by DiTom Microwave. The series targets microwave applications requiring reliable signal isolation and directionality. Similar variants in the family may differ in VSWR ratings or connector types while maintaining the same core frequency range and power handling capabilities.

RF Circulators And Isolators Replacement Considerations

Direct substitutes within the same series include D4C3742-2, D4C3742-3, and D4C3742-4. These alternatives share the 3.7–4.2 GHz frequency range and 20 W power rating but may exhibit different VSWR values, such as 1.15 or 1.2. Verify connector compatibility and electrical tolerances before substitution.
