D3I2428-3

RF Circulators And Isolators Overview

The D3I2428-3 is a single junction RF isolator manufactured by DiTom Microwave, designed for operation within the 24.00 to 28.00 GHz frequency range. It features a 2.92mm male-to-male connector configuration and operates as an in-line module. The component supports a maximum average forward power of 5 W. Key electrical specifications include a minimum isolation of 20 dB and a maximum voltage standing wave ratio (VSWR) of 1.25. The physical dimensions are 0.5 inches by 0.5 inches by 0.7 inches, with an operating temperature range from -20°C to +65°C.

RF Circulators And Isolators Feature Summary

• Provides high isolation performance with a minimum rating of 20 dB within the designated millimeter-wave frequency band.
• Utilizes a robust 2.92mm male connector interface on both input and output ports for secure signal transmission.
• Engineered as a single junction device to ensure unidirectional signal flow and protect source components.

RF Circulators And Isolators Applications

• Millimeter-wave communication systems requiring signal directionality
• Test and measurement instrumentation setups
• Satellite communication ground stations

RF Circulators And Isolators Procurement Notes

Verify the specific connector gender configuration matches the system requirements, as this model utilizes male connectors on both ends. Confirm that the 5 W power handling capability aligns with the operational load. Ensure the operating temperature range of -20°C to +65°C is suitable for the intended environment. Cross-reference the datasheet for precise insertion loss values not listed in the summary. Check RoHS compliance status if environmental regulations apply to the project.

RF Circulators And Isolators Selection Notes

Select this component when a dedicated isolator is required for the 24 to 28 GHz spectrum. The 2.92mm interface ensures compatibility with standard precision microwave test equipment. Consider the 20 dB isolation minimum for applications demanding significant reverse signal suppression. Evaluate the physical size constraints against available panel space. Compare VSWR specifications against other models if strict impedance matching is critical for system efficiency.

RF Circulators And Isolators Part Context

This part belongs to the D3I2428 series of RF isolators produced by DiTom Microwave. The series focuses on millimeter-wave frequencies, specifically targeting the 24 to 28 GHz band. Variations within the series may differ in connector gender or specific electrical tolerances. The D3I2428-3 represents the male-to-male variant, distinguishing it from female configurations found in related models like the D3I2428.

RF Circulators And Isolators Replacement Considerations

Direct substitutes within the same series include the D3I2428, which shares identical electrical specifications but features female connectors. Verify connector compatibility before swapping. Other manufacturers' products covering the 24-28 GHz range may serve as alternatives if mechanical interfaces can be adapted. Ensure replacement parts meet or exceed the 20 dB isolation and 5 W power ratings.
