D3C4043-7

RF Circulators And Isolators Overview

The D3C4043-7 is a single-junction RF circulator manufactured by DiTom Microwave, designed for millimeter-wave applications. It operates within the 40 GHz to 43.5 GHz frequency range and features Type-K female connectors on all three ports. The component supports an average forward power of 5 W, with a maximum insertion loss of 1.2 dB and isolation of 18 dB. Voltage Standing Wave Ratio (VSWR) is maintained at 1.5. The physical dimensions are 0.5 in x 0.5 in x 0.7 in, housed in a module package. Operating temperatures range from -20°C to +65°C.

RF Circulators And Isolators Procurement Notes

Verify the specific suffix configuration against official DiTom Microwave documentation to ensure correct connector type and pinout compatibility. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Cross-reference the datasheet for precise mechanical tolerances and thermal management specifications to validate system integration constraints.

RF Circulators And Isolators Selection Notes

Select this model when a three-port circulator is required for the 40–43.5 GHz spectrum with Type-K interface compatibility. Evaluate the 5 W power handling and 1.2 dB insertion loss limits against system link budget requirements. Ensure the operating temperature range of -20°C to +65°C aligns with the environmental conditions of the intended deployment scenario.

RF Circulators And Isolators Part Context

This component belongs to the D3C4043 series of RF circulators from DiTom Microwave. Variants within this family, such as D3C4043Q and D3C4043-3, differ primarily in connector types, including Type-N or mixed configurations. The D3C4043-7 specifically utilizes Type-K female connectors across all ports, distinguishing it from other series members while maintaining identical core electrical performance parameters.

RF Circulators And Isolators Replacement Considerations

Direct substitutes include D3C4043 and D3C4043-3, provided the connector interface matches the system design. Verify that alternative part numbers maintain the same 40–43.5 GHz frequency range and 5 W power rating. Mechanical footprint compatibility must be confirmed before substitution.
