RF Circulators And Isolators Procurement Notes

Verify that the specific connector configuration matches the system interface requirements, as this model supports both SMA-FEMALE and SMA-MALE options. Confirm that the MIL-AERO qualification status meets the project's reliability standards. Ensure the thermal environment is compatible with the module design. Cross-reference the exact part number suffix to avoid confusion with similar variants in the D3C or D4C series. Check current availability through authorized distributors.

RF Circulators And Isolators Selection Notes

Select this component when a ruggedized circulator is required for aerospace platforms operating between 8 and 12.4 GHz. The 25 W power rating makes it suitable for moderate-power transmission paths. Consider the physical dimensions and connector orientation during PCB or chassis layout. Compare VSWR and isolation metrics against other models if tighter performance margins are needed for sensitive receiver chains.

RF Circulators And Isolators Part Context

DiTom Microwave specializes in ferrite isolators and circulators for the Space and Defense markets, holding AS9100 Rev C certification. The company provides both commercial-off-the-shelf and high-reliability products ranging from 400 MHz to 40 GHz.
