D4I0555-2

RF Circulators And Isolators Overview

The DiTom Microwave D4I0555-2 is a dual junction coaxial isolator designed for the 500 MHz to 550 MHz frequency range. It features SMA-FEMALE connectors and operates within a module package configuration. The component supports an average forward power of 300 W, providing 40 dB of isolation with an insertion loss of 0.8 dB. Voltage Standing Wave Ratio (VSWR) is specified at 1.25. The device complies with ROHS3 standards and carries an ECCN classification of EAR99.

RF Circulators And Isolators Feature Summary

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

RF Circulators And Isolators Applications

• RF signal transmission systems requiring unidirectional flow

RF Circulators And Isolators Procurement Notes

Verify the specific suffix against official DiTom Microwave documentation to confirm functional equivalence, as ordering suffixes may alter specifications. Confirm RoHS3 compliance status and EAR99 export classification requirements prior to acquisition. Ensure SMA-FEMALE connector compatibility with existing system interfaces. Validate that the 300 W power rating meets operational thermal constraints.

RF Circulators And Isolators Selection Notes

Select this model when high isolation levels are required in the 500-550 MHz band. The dual junction architecture offers superior performance compared to single-junction variants. Consider the 0.8 dB insertion loss impact on system gain budgets. Verify physical dimensions and mounting requirements for the module package. Ensure the SMA-FEMALE interface matches downstream component connections.
