D4I2040-2

RF Circulators And Isolators Overview

The D4I2040-2 is a radio frequency isolator manufactured by DiTom Microwave, designed for operation within the 2.00 to 4.00 GHz frequency range. It features SMA-FEMALE connectors and utilizes a module package with SMA connector configuration. The component supports an average forward power of 20 W. Key electrical specifications include an isolation rating of 36 dB, an insertion loss of 1 dB, and a voltage standing wave ratio (VSWR) of 1.3.

RF Circulators And Isolators Feature Summary

• Provides high-directional signal isolation using a dual-port architecture with SMA-FEMALE interfaces.
• Engineered for stable performance across the 2 to 4 GHz microwave spectrum.
• Constructs a robust module form factor suitable for integration into RF transmission lines.

RF Circulators And Isolators Applications

• RF transmitter output stages requiring signal reflection protection
• Microwave communication systems operating in the 2-4 GHz band
• Test and measurement equipment needing isolated signal paths

RF Circulators And Isolators Procurement Notes

Verify the specific datasheet version for the D4I2040-2 to confirm exact mechanical dimensions and thermal characteristics. Ensure that the SMA-FEMALE connector compatibility matches the system interface requirements. Cross-reference the 20 W power handling and 36 dB isolation ratings against the application's peak power demands to prevent device failure. Confirm RoHS compliance status if environmental regulations apply to the final assembly.

RF Circulators And Isolators Selection Notes

Select this model when a 20 W power handling capability and 36 dB isolation are required within the 2-4 GHz range. The 1 dB insertion loss offers a balance between signal attenuation and isolation performance. Consider the SMA-FEMALE interface for standard coaxial connections. Compare against the D4C2040 series if circulator functionality is needed instead of single-direction isolation.

RF Circulators And Isolators Part Context

The D4I2040-2 belongs to the DiTom Microwave D4I series of RF isolators. This series focuses on providing reliable signal directionality for microwave applications. The product line includes variants such as the D4I2040 and D4I2040-1, which share similar frequency ranges but may differ in connector configurations or specific electrical tolerances. The D4I2040-2 specifically denotes the variant with defined 36 dB isolation and 1 dB insertion loss parameters.

RF Circulators And Isolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with existing SMA-FEMALE interfaces before considering alternative models from other manufacturers.
