D4C2040-4

RF Circulators And Isolators Overview

The DiTom Microwave D4C2040-4 is a dual junction RF circulator operating within the 2.00 to 4.00 GHz frequency range. This four-port device features mixed connector interfaces, specifically three SMA female ports and one SMA male port. It is designed for robust performance with an average forward power rating of 20 W, insertion loss of 0.5 dB, isolation of 18 dB, and a VSWR of 1.3. The unit operates between 0°C and +50°C, housed in a module package measuring 3.16 x 0.7 x 1.62 inches.

RF Circulators And Isolators Feature Summary

• Dual junction coaxial architecture providing high isolation capabilities
• Mixed interface configuration with three female and one male SMA connectors
• High power handling capacity suitable for demanding RF applications

RF Circulators And Isolators Applications

• RF signal routing in communication systems
• Transmitter and receiver separation in radar setups
• Test and measurement instrumentation circuits

RF Circulators And Isolators Procurement Notes

Verify specific connector orientation requirements due to the mixed male and female SMA interface configuration. Confirm thermal management needs as the device operates up to 50°C. Ensure system impedance matches the standard 50 Ohm specification inherent to this component series. Check RoHS compliance status directly with the manufacturer for final integration approval.

RF Circulators And Isolators Selection Notes

Select this model when a four-port circulator with mixed connector types is required for the 2-4 GHz band. Consider the dual junction design for enhanced isolation compared to single junction alternatives. Evaluate physical space constraints against the 3.16-inch length dimension. Compare power ratings if higher than 20 W average forward power is necessary.

RF Circulators And Isolators Part Context

This component belongs to the D4C2040 series from DiTom Microwave, which includes variants like D4C2040, D4C2040-1, and D4C2040-3. These models share similar frequency ranges and core technologies but differ in connector configurations and specific electrical parameters such as isolation levels. The series represents a line of dual junction coaxial circulators.

RF Circulators And Isolators Replacement Considerations

The D4C2040-1 and D4C2040-3 are related series components but feature all-female SMA connectors, differing from the mixed interface of the D4C2040-4. Direct substitution requires verifying connector compatibility with existing PCB or cable assemblies. Electrical performance metrics are comparable across the series.
