D4C1112-5

RF Circulators And Isolators Overview

The DiTom Microwave D4C1112-5 is a four-port dual junction RF circulator designed for the 10.7 GHz to 11.7 GHz frequency range. It features SMA female connectors on three ports and one SMA male connector, housed in a module package. The component supports an average forward power of 10 W with a maximum insertion loss of 0.3 dB. It provides an isolation level of 23 dB and maintains a voltage standing wave ratio (VSWR) of 1.2.

RF Circulators And Isolators Feature Summary

• Dual junction architecture providing enhanced signal routing capabilities within a compact module form factor.
• Mixed connector configuration utilizing three SMA female ports and one SMA male port for flexible system integration.

RF Circulators And Isolators Applications

• Microwave communication systems requiring directional signal flow control
• Radar transponder circuits operating within the specified Ku-band frequencies
• Test and measurement instrumentation setups needing low-loss signal circulation

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration against design requirements, as this model utilizes a mixed SMA interface scheme. Confirm that the 10 W average power rating aligns with the thermal management capabilities of the target application environment. Ensure compatibility with standard SMA mating hardware for the female ports.

RF Circulators And Isolators Selection Notes

Select this component when a dual junction topology is required for improved isolation characteristics compared to single junction alternatives. Consider the mixed male-female connector arrangement during PCB or cable assembly design to ensure proper physical alignment. Validate that the 10.7–11.7 GHz operational band matches the system's center frequency and bandwidth constraints.

RF Circulators And Isolators Part Context

This part belongs to the D4C1112 series of microwave circulators manufactured by DiTom Microwave. The series typically offers high-performance RF isolation and low insertion loss for applications in the 10–12 GHz range. Variations within the series may differ in connector types or power handling capabilities while maintaining similar core electrical specifications.

RF Circulators And Isolators Replacement Considerations

The D3C1112-5 is a documented alternative within the same product family, offering identical frequency and electrical performance but potentially differing in connector configuration or internal junction structure. Verify mechanical fit and pinout compatibility before substitution.
