D4C0112-5

RF Circulators And Isolators Overview

The D4C0112-5 is a four-port RF circulator manufactured by DiTom Microwave, designed for operation within the 1.2 GHz to 1.4 GHz frequency range. This dual junction device features SMA female connectors on three ports and one SMA male connector. It supports an average forward power of 10 W, with a maximum isolation of 23 dB and a typical insertion loss of 0.3 dB. The voltage standing wave ratio (VSWR) is specified at 1.2. The component is housed in a module package with SMA connectors and complies with RoHS3 standards.

RF Circulators And Isolators Feature Summary

• Dual junction construction providing high isolation between ports
• Low insertion loss characteristics for efficient signal transmission
• Mixed connector configuration with three female and one male SMA interfaces

RF Circulators And Isolators Applications

• RF signal routing in communication systems
• Transmitter-receiver switching applications
• Antenna sharing networks

RF Circulators And Isolators Procurement Notes

Verify the specific connector orientation and pinout against the official datasheet before integration, as the mixed SMA configuration requires precise mating compatibility. Confirm that the 10 W power rating aligns with peak system demands. Ensure environmental compliance requirements match the RoHS3 status documented in the manufacturer specifications.

RF Circulators And Isolators Selection Notes

Select this model when a compact circulator is required for the 1.2–1.4 GHz band with moderate power handling. The dual junction design offers superior isolation compared to single-junction alternatives. Consider the mixed SMA connector types for interface flexibility in custom assembly designs requiring both male and female connections.

RF Circulators And Isolators Part Context

This component belongs to the D4C series of RF circulators from DiTom Microwave. The series includes variants covering different frequency bands and power levels. The D4C0112-5 specifically targets the lower UHF/L-band spectrum, distinguishing it from higher-frequency models like the D4C1112-5 or wider-bandwidth options such as the D4C7011-3.

RF Circulators And Isolators Replacement Considerations

D3C0112-5: Similar frequency range but may differ in power handling or isolation specifications; verify datasheet details.
