D3I4042Q-2

RF Circulators And Isolators Overview

The D3I4042Q-2 is a single-junction RF isolator manufactured by DiTom Microwave, designed for operation within the 40 GHz to 42 GHz frequency range. It utilizes 2.4mm connectors with female and male gender configuration. The component supports an average forward power of 5 W and provides 20 dB of isolation. Key electrical specifications include a maximum insertion loss of 0.8 dB and a voltage standing wave ratio (VSWR) of 1.25. The device operates reliably between -20°C and +65°C.

RF Circulators And Isolators Feature Summary

• Provides directional signal transmission with high isolation in the E-band spectrum
• Utilizes robust 2.4mm connector interface for precise microwave coupling
• Engineered as a single-junction module for stable RF performance

RF Circulators And Isolators Applications

• E-band wireless communication systems
• Microwave test and measurement instrumentation
• Satellite ground station uplink/downlink chains

RF Circulators And Isolators Procurement Notes

Verify the specific connector gender configuration required for your system architecture, as the D3I4042Q series includes variants with different pin arrangements. Confirm that the operating temperature range of -20°C to +65°C aligns with your environmental conditions. Ensure compatibility with 2.4mm mating interfaces to maintain optimal VSWR and insertion loss performance during integration.

RF Circulators And Isolators Selection Notes

Select this model when a dedicated isolator is needed for the 40-42 GHz band with moderate power handling capabilities. Consider the physical dimensions and mounting requirements associated with the module package. Evaluate whether the 20 dB isolation level meets the noise floor requirements of your specific receiver or transmitter chain compared to higher-isolation alternatives.

RF Circulators And Isolators Part Context

This component belongs to the D3I4042Q series of microwave isolators from DiTom Microwave. The series covers the 40-42 GHz frequency range, offering consistent electrical performance across different connector configurations. It serves as a critical passive component for protecting sensitive sources from reflected power in high-frequency applications.

RF Circulators And Isolators Replacement Considerations

Direct substitutes within the same series include D3I4042Q-1 and D3I4042Q-3. Verify connector gender compatibility before substitution, as these variants differ in pin orientation while maintaining identical electrical specifications.
