• Mixed port configuration accommodating varied interface requirements
• Robust thermal performance across standard industrial temperature ranges

RF Circulators And Isolators Applications

• Microwave communication systems
• Test and measurement instrumentation
• Radar subsystems

RF Circulators And Isolators Procurement Notes

Verify specific connector configurations against project requirements due to the mixed male/female port arrangement. Confirm RoHS3 compliance status through official documentation prior to integration. Ensure operating temperatures remain within the specified -20°C to +65°C limits during deployment. Cross-reference datasheet parameters for insertion loss and isolation to validate system performance needs.

RF Circulators And Isolators Selection Notes

Select this model when a four-port circulator is required for high-frequency applications between 18 GHz and 40 GHz. Consider the dual junction architecture for improved isolation characteristics compared to single-junction alternatives. Evaluate the physical footprint of 1x0.5x0.7 inches for PCB or chassis space constraints. Verify that the mixed connector types align with existing cable assemblies or adapter solutions.

RF Circulators And Isolators Part Context

This component belongs to the D4C1840 series from DiTom Microwave, which specializes in microwave passive components. The series includes various isolators and circulators covering similar frequency bands. The D4C1840-4 variant specifically denotes the four-port configuration with distinct connector arrangements, differentiating it from three-port isolator models like the D4I1840-3.

RF Circulators And Isolators Replacement Considerations

The D4C1840-3 serves as a related part number within the same product family, offering comparable frequency coverage but potentially differing in port count or connector specifications. Verify electrical parameters and mechanical dimensions before substitution.
