D3C1218

RF Circulators And Isolators Overview

The DiTom Microwave D3C1218-4 is a three-port RF circulator designed for the 12 GHz to 18 GHz frequency range. It features SMA female connectors and operates within a module package measuring 0.5 inches by 0.5 inches by 0.7 inches. The component supports an average forward power of 5 W, with a maximum insertion loss of 0.45 dB and isolation of 22 dB. Voltage Standing Wave Ratio (VSWR) is specified at 1.25. The device complies with RoHS3 standards and carries an EAR99 classification.

RF Circulators And Isolators Feature Summary

• Provides directional signal flow control in the Ku-band spectrum
• Utilizes SMA female interface connectors for system integration
• Constructed in a compact rectangular module housing

RF Circulators And Isolators Applications

• RF signal routing in communication systems
• Transmitter-receiver separation in radar architectures
• Antenna duplexing applications

RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation required for the project, as variants such as -1, -2, -3, -4, and -5 exist within the D3C1218 series. Confirm that the SMA female connector configuration aligns with the system interface requirements. Ensure the 5 W power handling capacity meets the operational load. Check for RoHS3 compliance documentation if environmental regulations apply. Validate the physical dimensions against available board space constraints.

RF Circulators And Isolators Selection Notes

Select this component when a non-reciprocal three-port network is needed between 12 GHz and 18 GHz. The low insertion loss of 0.45 dB minimizes signal attenuation. The 22 dB isolation rating ensures effective port separation. The SMA female interface simplifies connection to standard coaxial cables. Consider the 0.5 x 0.5 x 0.7 inch footprint for size-sensitive designs.

RF Circulators And Isolators Part Context

The D3C1218 series belongs to DiTom Microwave's portfolio of RF circulators and isolators. These components are engineered for high-frequency applications requiring precise signal directionality. The family includes multiple suffix variations, all sharing the core 12-18 GHz operational band and similar electrical characteristics. They serve as critical passive elements in microwave circuit design.
