D4C0555-4

RF Circulators And Isolators Overview

The D4C0555-4 is a coaxial circulator manufactured by DiTom Microwave, 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 with an isolation rating of 20 dB. Key electrical specifications include an insertion loss of 0.4 dB and a Voltage Standing Wave Ratio (VSWR) of 1.25. The device complies with RoHS3 standards and carries an ECCN classification of EAR99.

RF Circulators And Isolators Feature Summary

• Provides directional signal flow control in the VHF band using a three-port coaxial architecture.
• Maintains low signal attenuation through optimized internal magnetic circuit design.
• Ensures high port-to-port isolation to prevent signal interference between input and output paths.

RF Circulators And Isolators Applications

• Transmitter-receiver duplexing in communication systems
• Antenna sharing networks requiring signal isolation
• Test and measurement equipment RF signal routing

RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm connector type and performance tolerances. Ensure that the operating environment remains within the specified thermal limits to maintain the rated 300 W power handling capability. Confirm RoHS3 compliance requirements align with project regulations before finalizing procurement orders.

RF Circulators And Isolators Selection Notes

Select this component when a fixed frequency operation between 500 MHz and 550 MHz is required. The SMA female interface dictates compatibility with existing cable assemblies. Consider the 0.4 dB insertion loss and 1.25 VSWR values for system link budget calculations. Verify that the physical module dimensions fit the intended enclosure space.

RF Circulators And Isolators Part Context

This model belongs to the D4C series of dual-junction coaxial circulators from DiTom Microwave. The series is engineered for robust performance in radio frequency applications. The base part number D4C0555 defines the core frequency and power characteristics, while the suffix indicates specific connector or packaging variations.

RF Circulators And Isolators Replacement Considerations

Cross-reference with other DiTom models in the D4C series for similar frequency ranges. Verify that substitute parts match the SMA female connector configuration and 300 W power rating. Ensure replacement components meet the same 20 dB isolation and 1.25 VSWR specifications to maintain system integrity.
