D3C0555-6

RF Circulators And Isolators Overview

The DiTom Microwave D3C0555-6 is a three-port RF circulator designed for the 500 MHz to 550 MHz frequency range. It features SMA female connectors and supports an average forward power rating of 300 W. Key electrical specifications include a maximum insertion loss of 0.3 dB, isolation of 23 dB, and a voltage standing wave ratio (VSWR) of 1.25. The unit operates within a temperature range of -20°C to +65°C and utilizes passivated stainless steel construction with gold-plated contacts.

RF Circulators And Isolators Feature Summary

• Provides non-reciprocal signal routing across three ports using ferrite technology
• Ensures high signal integrity through low insertion loss and stable impedance matching
• Supports high-power transmission applications with robust thermal management capabilities

RF Circulators And Isolators Applications

• RF communication systems requiring signal directionality
• Transmitter output protection circuits
• Antenna switching networks in radar or telemetry systems

RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation when ordering, as variants such as D3C0555-6 may differ from the base model D3C0555. Confirm connector type compatibility and power ratings against system requirements. Check current availability status as distribution channels may report limited stock or extended lead times. Ensure environmental compliance documentation matches project specifications.

RF Circulators And Isolators Selection Notes

Select this component based on its specific 500-550 MHz operational bandwidth and 300 W power handling capacity. Evaluate the 23 dB isolation specification against system noise floor requirements. Consider the SMA female interface for cable integration. Assess physical dimensions and mounting style relative to enclosure constraints. Verify temperature range suitability for the intended operating environment.

RF Circulators And Isolators Part Context

This part belongs to the DiTom Microwave D3C0555 series of connectorized ferrite circulators. The series covers frequencies from 400 MHz to 43.5 GHz. The D3C0555-6 variant specifically targets the VHF band with standardized SMA interfaces. DiTom Microwave manufactures these components for high-reliability RF applications requiring precise signal control.

RF Circulators And Isolators Replacement Considerations

Direct substitutes are not explicitly listed in public documentation. Cross-reference models must match the 500-550 MHz frequency range, 300 W power rating, and SMA female connectivity. Verify that alternative parts meet or exceed the 23 dB isolation and 1.25 VSWR specifications.
