D3I3743-1

RF Circulators And Isolators Overview

The D3I3743-1 is an RF isolator manufactured by DiTom Microwave, designed for operation within the 37 GHz to 43 GHz frequency range. It features a Type-K female connector interface and utilizes a module package configuration. The component supports a maximum average forward power of 5 W. Key electrical specifications include an insertion loss of 1.2 dB, an isolation rating of 14 dB, and a voltage standing wave ratio (VSWR) of 1.35. The device operates within a temperature range of -20°C to +65°C and measures 0.5 inches by 0.5 inches by 0.7 inches.

RF Circulators And Isolators Feature Summary

• Provides signal isolation in the 37 GHz to 43 GHz band
• Features a single junction design for directional signal control
• Utilizes a robust module package with Type-K female connectors

RF Circulators And Isolators Applications

• High-frequency microwave communication systems
• Test and measurement instrumentation requiring signal isolation
• Satellite communication uplink/downlink chains

RF Circulators And Isolators Procurement Notes

Verify the specific connector type and physical dimensions against system requirements before ordering. Confirm RoHS compliance status and manufacturing origin details through official distributor channels. Ensure that the operating temperature range aligns with the intended environmental conditions. Check for any specific handling instructions related to the module packaging to prevent damage during installation.

RF Circulators And Isolators Selection Notes

Select this component when a fixed frequency isolator is required for the 37-43 GHz spectrum. Consider the 5 W power handling capability and 14 dB isolation level as primary selection criteria. Evaluate the Type-K connector compatibility with existing circuit board layouts or cable assemblies. Compare the module form factor against space constraints in the final assembly design.

RF Circulators And Isolators Part Context

This part belongs to the DiTom Microwave D3I series of RF isolators. It shares similar electrical performance characteristics with other models in the family but differs in connector type and specific mechanical footprint. The series is designed for high-reliability applications in microwave frequencies, offering consistent isolation and low insertion loss across the designated bandwidth.

RF Circulators And Isolators Replacement Considerations

Direct substitutes may include the D3I3743Q-1, which offers identical electrical specifications but utilizes a 2.4mm female connector instead of Type-K. Verify mechanical fit and connector mating compatibility when considering alternative part numbers from the same manufacturer.
