• Quantum computing readout chains

RF Circulators And Isolators Procurement Notes

Verify the specific datasheet version for the D4C8012Y-3, as it is listed as discontinued in some channels. Confirm mechanical dimensions and soldering profiles against the official DiTom Microwave drawing to ensure compatibility with existing PCB layouts. Check RoHS compliance status directly with the manufacturer or authorized distributors before finalizing procurement plans.

RF Circulators And Isolators Selection Notes

Select this component when a four-port circulator is required for applications operating below standard room temperature. The dual junction architecture provides enhanced isolation compared to single-junction variants. Ensure the system can accommodate the specified module dimensions and that the SMA male interface matches the board-to-board or cable interconnect requirements.

RF Circulators And Isolators Part Context

This part belongs to the D4C8012Y series of cryogenic circulators from DiTom Microwave. It shares the same frequency range and core technology as other models in the family but differs in port configuration and connector type. It is distinct from the D3C8012 series which typically uses female connectors and may have different thermal optimization targets.

RF Circulators And Isolators Replacement Considerations

Public confirmed substitutes are not available due to the discontinued status. Evaluate equivalent cryogenic circulators from other manufacturers if supply chain continuity is critical. Ensure any alternative meets the 8-12 GHz bandwidth and 25 W power handling requirements.
