D4I0555

RF Circulators And Isolators Overview

The D4I0555 is a dual junction coaxial isolator manufactured by DiTom Microwave, designed for the 500 MHz to 550 MHz frequency range. It features SMA-FEMALE connectors and operates within a temperature range of -20°C to +65°C. Key electrical specifications include an average forward power rating of 300 W, isolation of 40 dB, insertion loss of 0.8 dB, and a VSWR of 1.25. The component is housed in a module package with dimensions of 3.16 inches by 0.73 inches by 1.62 inches.

RF Circulators And Isolators Feature Summary

• Dual junction coaxial design for enhanced RF performance
• High average forward power handling capability
• SMA-FEMALE connector interface for standard integration

RF Circulators And Isolators Applications

• RF signal transmission systems requiring unidirectional flow
• Protection of sensitive RF sources from reflected power
• Microwave communication equipment operating in the 500-550 MHz band

RF Circulators And Isolators Procurement Notes

Verify the specific suffix variant (e.g., D4I0555-1, D4I0555-3) against application requirements, as connector configurations may differ between models. Confirm RoHS3 compliance status and export classification EAR99 for regulatory adherence. Ensure thermal management aligns with the specified -20°C to +65°C operating range during system integration.

RF Circulators And Isolators Selection Notes

Select this model when high isolation (40 dB) and moderate insertion loss (0.8 dB) are critical for system efficiency. The 300 W power rating suits applications demanding robust power handling. Compare with circulator variants like D4C0555 if multi-port functionality is required instead of single-direction isolation.

RF Circulators And Isolators Part Context

The D4I0555 belongs to the DiTom Microwave D4I series of RF isolators. It is part of a family including variants such as D4I0555-1 and D4I0555-3, which share core electrical characteristics but may differ in physical connector types or packaging. This series targets microwave applications requiring reliable signal directionality.

RF Circulators And Isolators Replacement Considerations

Direct substitutes within the same series include D4I0555-1 and D4I0555-2. Verify connector compatibility, as some variants use Male-Male configurations while others use SMA-FEMALE. Cross-reference with D4C0555 series only if circulator functionality is acceptable.
