RF Circulators And Isolators Procurement Notes

Verify the specific suffix configuration against official DiTom Microwave documentation to ensure compatibility with system requirements. Confirm that the Type-N female interface matches the intended circuit board or cable assembly. Check current RoHS3 compliance status and export control classifications prior to finalizing procurement orders.

RF Circulators And Isolators Selection Notes

Select this model when a three-port circulator is required for the 37 GHz to 43 GHz band. Ensure the application demands a 5 W power handling capability and accepts a 14 dB isolation level. Verify that the physical dimensions fit the available space constraints and that the operating temperature range aligns with environmental conditions.

RF Circulators And Isolators Part Context

This component belongs to the D3C series of RF circulators from DiTom Microwave. It shares core performance characteristics with other variants in the family but differs in connector type and specific frequency sub-bands. The Q-series designation typically indicates specific packaging or connector configurations distinct from non-Q variants.

RF Circulators And Isolators Replacement Considerations

D3C3743-1: Offers similar performance but uses Type-K female connectors instead of Type-N. D3C3743Q-3: Provides identical electrical specifications and frequency range but utilizes different connector arrangements. Verify mechanical footprint and connector gender before substitution.
