D3I4042-1

RF Circulators And Isolators Overview

The D3I4042-1 is a single-junction RF isolator manufactured by DiTom Microwave, designed for operation within the 40.00 GHz to 42.00 GHz frequency range. This component utilizes Type-K female connectors and is housed in a module package with dimensions of 0.5 inches by 0.5 inches by 0.7 inches. It supports an average forward power of 5 W while maintaining an insertion loss of 0.8 dB. The device provides 20 dB of isolation and exhibits a voltage standing wave ratio (VSWR) of 1.25. It operates reliably between -20°C and +65°C and complies with RoHS3 standards.

RF Circulators And Isolators Feature Summary

• Provides directional signal transmission with high isolation in the 40-42 GHz band
• Utilizes Type-K female connectors for standardized interface compatibility
• Engineered as a single-junction module for compact integration

RF Circulators And Isolators Applications

• Millimeter-wave communication systems
• Satellite ground station equipment
• High-frequency radar test setups

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and physical dimensions against system requirements before ordering. Confirm that the Type-K female interface matches the mating hardware in the assembly. Ensure the operating temperature range of -20°C to +65°C aligns with the environmental conditions of the intended application. Check current availability status as lead times may vary due to manufacturing schedules.

RF Circulators And Isolators Selection Notes

Select this model when a 40-42 GHz isolator with Type-K interfaces is required. Consider the 5 W power handling limit and 0.8 dB insertion loss for system budget calculations. Compare against the D3I4042Q-3 if male connectors are needed instead of female. Evaluate the module size constraints against available board space. Verify RoHS3 compliance if environmental regulations apply to the project.

RF Circulators And Isolators Part Context

This component belongs to the D3I4042 series of RF circulators and isolators from DiTom Microwave. The series covers millimeter-wave frequencies with various connector options. The D3I4042-1 specifically denotes the version with Type-K female connectors. Related models include the D3I4042Q-3 with male connectors and the D3I4043-1 covering a slightly different frequency range.

RF Circulators And Isolators Replacement Considerations

The D3I4042Q-3 serves as a substitute with identical electrical performance but uses male connectors. The D3I4043-1 offers similar features but operates up to 43.5 GHz. Verify connector gender and frequency overlap before swapping components.
