D4I1213

RF Circulators And Isolators Overview

The DiTom Microwave D4I1213 is an RF isolator designed for the K-band frequency range of 11.7 GHz to 12.7 GHz. It features SMA-FEMALE connectors and operates with an average forward power rating of 10 W. Key electrical specifications include a maximum insertion loss of 0.6 dB, an isolation level of 46 dB, and a voltage standing wave ratio (VSWR) of 1.2. The component is housed in a module package with integrated SMA connectors.

RF Circulators And Isolators Feature Summary

• Provides high isolation of 46 dB within the specified frequency band
• Supports 10 W average forward power handling capacity
• Utilizes SMA-FEMALE connector interface for integration

RF Circulators And Isolators Applications

• Microwave communication systems requiring signal directionality
• Test and measurement equipment needing source protection
• Satellite ground station receiver chains

RF Circulators And Isolators Procurement Notes

Verify the specific suffix variant required, as the base model D4I1213 may have distinct ordering codes such as D4I1213-1 or D4I1213-2. Confirm that the SMA-FEMALE configuration matches the system interconnect requirements. Ensure compliance with RoHS3 standards if environmental regulations apply to the deployment environment.

RF Circulators And Isolators Selection Notes

Select this component when a fixed-frequency isolator is needed for the 11.7–12.7 GHz range. The 10 W power rating suits moderate power applications. Compare against circulator models like D4C1213 if multi-port functionality is required instead of two-way isolation. Verify VSWR limits meet system return loss budgets.

RF Circulators And Isolators Part Context

This part belongs to the DiTom Microwave D4I series of thermal vacuum coaxial ferrite isolators. These components are engineered for reliability in demanding environments, including those with low pressure conditions below 5x10^-5 torr. The series supports various connector configurations and power levels tailored for microwave subsystems.

RF Circulators And Isolators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Variants such as D4I1213-1 or D4I1213-2 may represent different packaging or minor specification adjustments; verify datasheet equivalence before substitution.
