D3I4042Q-1

RF Circulators And Isolators Overview

The D3I4042Q-1 is a single-junction RF isolator manufactured by DiTom Microwave, designed for operation within the 40.00 GHz to 42.00 GHz frequency range. It features a 2.4mm female connector interface and is housed in a module package. The component supports an average forward power of 5 W, providing 20 dB of isolation with an insertion loss of 0.8 dB and a VSWR of 1.25. It complies with RoHS3 standards and operates under MSL level 1 conditions.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission with high reverse isolation in the E-band spectrum
• Utilizes a robust 2.4mm female connector interface for precise microwave interconnects
• Engineered as a single-junction module for stable performance under specified power loads

RF Circulators And Isolators Applications

• E-band radar systems requiring signal directionality
• Microwave communication links operating between 40 and 42 GHz
• Test and measurement instrumentation for high-frequency characterization

RF Circulators And Isolators Procurement Notes

Verify the specific connector gender and mating compatibility before integration, as variants such as the D3I4042Q-3 utilize male connectors despite sharing the base series designation. Confirm that the 2.4mm female interface aligns with the system's waveguide or coaxial transition requirements. Ensure the 5 W power rating meets the peak and average power demands of the application circuit without exceeding thermal limits defined in the official datasheet.

RF Circulators And Isolators Selection Notes

Select this component when a fixed-frequency isolator is required for the 40-42 GHz band with moderate power handling capabilities. The 2.4mm interface suits compact PCB or waveguide-to-coaxial transitions where low VSWR is critical. Consider the module form factor for ease of mounting compared to discrete components. Evaluate the 0.8 dB insertion loss against system noise budget constraints to ensure minimal signal degradation in the forward path.

RF Circulators And Isolators Part Context

This part belongs to the D3I4042Q series of RF isolators from DiTom Microwave. It shares the core frequency and power specifications with other variants in the family but differs in connector configuration. For instance, the D3I4042Q-3 variant utilizes male connectors, whereas the D3I4042Q-1 specifically employs female interfaces. This distinction dictates mechanical integration strategies within the host assembly.

RF Circulators And Isolators Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires verifying identical electrical parameters and mechanical footprint compatibility with existing system designs.
