D4C4450

RF Circulators And Isolators Overview

The D4C4450 is a DiTom Microwave RF circulator designed for the 4.4 GHz to 5.0 GHz frequency range. It features SMA-FEMALE connectors and operates within a module package configuration. The component supports an average forward power of 25 W with a maximum isolation of 23 dB. Key electrical performance metrics include an insertion loss of 0.3 dB and a voltage standing wave ratio (VSWR) of 1.15. The device complies with RoHS3 standards and carries an ECCN classification of EAR99.

RF Circulators And Isolators Feature Summary

• Provides directional signal routing via three-port circulator topology
• Ensures high port-to-port isolation to prevent signal reflection
• Maintains low insertion loss for efficient power transmission
• Supports high average forward power handling capabilities

RF Circulators And Isolators Applications

• RF front-end modules requiring signal directionality
• Transmitter-receiver separation in communication systems
• Test and measurement equipment signal paths
• Microwave circuit protection against reflected power

RF Circulators And Isolators Procurement Notes

Verify the specific connector gender and pin configuration against the official datasheet before integration, as suffix variations may exist within the product family. Confirm that the 25 W power rating aligns with your system's thermal management requirements. Ensure the SMA-FEMALE interface matches your PCB or cable assembly design. Check current availability status through authorized distributors, as lead times may vary based on manufacturing schedules.

RF Circulators And Isolators Selection Notes

Select this model when a robust circulator is needed for the 4.4-5.0 GHz band with moderate power handling. Compare the 25 W power rating against higher-power alternatives like the D3C4450 if system demands exceed this limit. Evaluate the 23 dB isolation specification against your system's noise floor requirements. Consider the SMA-FEMALE connector type for compatibility with standard microwave interconnects.

RF Circulators And Isolators Part Context

This component belongs to the D4C4450 series of RF circulators from DiTom Microwave. It shares similar frequency and connector specifications with related models such as the D4C4450-2 and D4C4450-4, which typically feature lower power ratings of 20 W. The D4C4450 distinguishes itself by offering a higher 25 W average forward power capacity while maintaining identical electrical performance characteristics regarding isolation and VSWR.

RF Circulators And Isolators Replacement Considerations

The D4C4450-2 and D4C4450-4 are confirmed substitutes within the same series but offer reduced power handling at 20 W. If higher power capacity is required, the D3C4450 serves as a compatible alternative with identical electrical specs but potentially different mechanical or ordering suffixes. Verify connector orientation and mounting requirements when swapping between these variants.
