D4C0890-4

RF Circulators And Isolators Overview

The DiTom Microwave D4C0890-4 is an active RF circulator designed for the 800 MHz to 900 MHz frequency range. It features SMA female connectors and operates within a module package configuration. The component supports an average forward power of 250 W, with a maximum insertion loss of 0.4 dB and isolation of 20 dB. Voltage Standing Wave Ratio (VSWR) is specified at 1.25. It complies with RoHS3 standards and carries an EAR99 classification.

RF Circulators And Isolators Feature Summary

• Provides non-reciprocal signal routing for three-port microwave applications
• Maintains low insertion loss and high isolation within the designated band
• Utilizes SMA female interfaces for standardized interconnection

RF Circulators And Isolators Applications

• Transmitter-receiver duplexing in communication systems
• Antenna switching networks
• Reflectometry measurement setups

RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation against official DiTom Microwave documentation to confirm connector orientation and mechanical tolerances. Ensure that the required operating frequency aligns precisely with the 800 MHz to 900 MHz specification. Confirm compliance requirements such as RoHS3 status match project constraints before finalizing procurement orders.

RF Circulators And Isolators Selection Notes

Select this model when a three-port circulator is required for the 800-900 MHz band with SMA connectivity. Consider the 250 W power handling capability and 20 dB isolation level relative to system requirements. Compare against similar models like D3C0890-4 if higher isolation or lower insertion loss is necessary for the application.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave D4C0890 series of RF circulators. The series offers variants with different isolation levels and connector configurations while maintaining the same core frequency range and power handling capabilities. It serves as a standard passive microwave component for signal direction control.

RF Circulators And Isolators Replacement Considerations

The D3C0890-4 offers identical frequency and power specifications but provides 23 dB isolation and 0.3 dB insertion loss. Verify mechanical compatibility and electrical parameter differences before substituting.
