D4I7018-3

RF Circulators And Isolators Overview

The D4I7018-3 is an RF isolator manufactured by DiTom Microwave, designed for operation within the 7 GHz to 18 GHz frequency range. It features SMA-FEMALE connectors and utilizes a module package with SMA connector configuration. The component supports an average forward power of 10 W. Key electrical specifications include an insertion loss of 1 dB, an isolation rating of 30 dB, and a Voltage Standing Wave Ratio (VSWR) of 1.5.

RF Circulators And Isolators Feature Summary

• Provides signal isolation in microwave circuits to prevent reflected energy from affecting source components
• Operates across a wide bandwidth spanning 7 GHz to 18 GHz
• Utilizes SMA-FEMALE interface connectors for standard integration

RF Circulators And Isolators Applications

• Microwave communication systems requiring signal directionality
• Test and measurement equipment setups
• Radar system front-end protection

RF Circulators And Isolators Procurement Notes

Verify the specific datasheet version for the D4I7018-3 model, as public sources indicate potential variations in isolation ratings between 15 dB and 30 dB. Confirm that the SMA-FEMALE connector type matches the system requirements. Ensure compliance with RoHS3 standards and check the MSL level 1 classification for handling procedures during assembly and storage.

RF Circulators And Isolators Selection Notes

Select this component when a wideband isolator covering 7 to 18 GHz is required. The 10 W average power rating suits moderate power applications. Consider the 30 dB isolation specification for effective noise reduction. The SMA-FEMALE interface ensures compatibility with standard coaxial test fixtures and circuit boards utilizing matching male connectors.

RF Circulators And Isolators Part Context

This part belongs to the DiTom Microwave D4I series of RF isolators. The series includes variants such as D4I7011-3 and D4I8018-3, which share similar modular construction but differ in frequency ranges and power handling capabilities. The D4I7018-3 specifically targets the broader C, X, and Ku band applications compared to narrower bandwidth alternatives.

RF Circulators And Isolators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify mechanical dimensions and pinout compatibility if considering alternative manufacturers' wideband isolators.
