D3I3742-3

RF Circulators And Isolators Overview

The D3I3742-3 is a single-junction RF isolator manufactured by DiTom Microwave, designed for operation within the 3.70 GHz to 4.20 GHz frequency range. It features SMA female connectors and operates at an average forward power of 20 W. Key electrical specifications include an insertion loss of 0.3 dB, isolation of 23 dB, and a VSWR of 1.2. The component is housed in a module package with SMA connectors, suitable for applications requiring signal directionality and protection in microwave systems.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission to protect source components from reflected power
• Utilizes a single-junction design for efficient microwave signal management
• Features SMA female connectors for standard interface compatibility

RF Circulators And Isolators Applications

• Microwave communication systems
• RF test and measurement equipment
• Signal generator output stages

RF Circulators And Isolators Procurement Notes

Verify the specific suffix '-3' against the manufacturer's datasheet to confirm connector configuration and mechanical dimensions. Ensure the required operating temperature range of -30°C to +65°C aligns with the system environment. Confirm RoHS3 compliance status if environmental regulations apply to the final assembly. Cross-reference the part number with official DiTom documentation to avoid confusion with similar variants like D3C3742-3 or D4I3742-3.

RF Circulators And Isolators Selection Notes

Select this isolator when a 3.7–4.2 GHz frequency band is required with high isolation capabilities. The 20 W power handling capacity suits moderate-power applications. Consider the SMA female interface for integration with existing cabling. Evaluate the 0.3 dB insertion loss impact on system efficiency. Compare against circulator alternatives if multi-port functionality is needed instead of two-port isolation.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave series of RF isolators and circulators. It is part of a family of passive microwave devices designed for signal integrity. The D3I3742-3 specifically addresses the need for directional control in the C-band spectrum. It complements other models like the D3C3742-3 circulator by providing isolated transmission paths.

RF Circulators And Isolators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify compatibility with direct replacements such as D4I3742-3 only if electrical parameters match exactly. Consult DiTom Microwave for updated equivalents.
