D4C1218-5

RF Circulators And Isolators Overview

The D4C1218-5 is a broadband circulator manufactured by DiTom Microwave, designed for operation within the 12.00 GHz to 18.00 GHz frequency range. This component features SMA-FEMALE connectors and utilizes a module package with integrated SMA interfaces. Key electrical specifications include an average forward power rating of 5 W, isolation of 22 dB, insertion loss of 0.45 dB, and a Voltage Standing Wave Ratio (VSWR) of 1.25. The device is classified as a ring circulator type and is currently in active production status.

RF Circulators And Isolators Feature Summary

• Provides signal circulation across a wide microwave bandwidth from 12 GHz to 18 GHz
• Ensures high isolation performance to protect source components from reflected energy
• Features low insertion loss characteristics for efficient signal transmission
• Utilizes robust SMA-FEMALE connector interface for reliable integration

RF Circulators And Isolators Applications

• Satellite communication systems requiring high-frequency signal routing
• Defense radar transmitters needing isolated signal paths
• Space qualification hardware for thermal vacuum environments

RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation against official DiTom Microwave documentation to confirm exact pinout and connector configuration. Ensure compatibility with system impedance requirements before integration. Confirm RoHS3 compliance status if environmental regulations apply to the end application. Cross-reference the part number with current manufacturer datasheets to validate active production status and technical parameters.

RF Circulators And Isolators Selection Notes

Select this model when a broadband circulator covering 12-18 GHz is required with moderate power handling capabilities. The 5 W average forward power rating suits applications where higher power levels are not critical. Consider the SMA-FEMALE interface for standard coaxial connections. Evaluate the 22 dB isolation specification against system noise floor requirements to ensure adequate protection for sensitive upstream components.
