D3I3841Q-2

RF Circulators And Isolators Overview

The D3I3841Q-2 is a microwave isolator manufactured by DiTom Microwave, designed for operation within the 38.00 GHz to 41.00 GHz frequency range. This component utilizes Type-N female connectors and is housed in a module package. It supports an average forward power of 5 W while maintaining a maximum insertion loss of 1 dB. The device provides 17 dB of isolation and achieves a Voltage Standing Wave Ratio (VSWR) of 1.3. It complies with RoHS3 standards and carries an ECCN classification of EAR99.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission to protect source components from reflected power
• Maintains low signal attenuation through minimal insertion loss characteristics
• Ensures impedance matching stability via controlled VSWR performance

RF Circulators And Isolators Applications

• Microwave communication systems requiring signal directionality
• Test and measurement equipment interfaces
• Satellite ground station uplink/downlink chains

RF Circulators And Isolators Procurement Notes

Verify the specific connector configuration and tolerance requirements against system schematics before ordering. Confirm that the 5 W power rating aligns with peak operational loads. Ensure environmental compliance with RoHS3 directives is required for the target assembly. Cross-reference the basic part number D3I3841 to confirm family compatibility. Validate that the module form factor fits the designated PCB or waveguide layout constraints.

RF Circulators And Isolators Selection Notes

Select this model when a 38-41 GHz frequency band is mandatory for the application. Choose based on the requirement for Type-N female connectivity over other interface types. Consider the 17 dB isolation level sufficient for the specific noise floor requirements. Evaluate the 5 W power handling capacity against the maximum expected transmit power. Compare the module packaging against available space constraints in the RF chain.

RF Circulators And Isolators Part Context

This component belongs to the D3I3841 series of microwave isolators produced by DiTom Microwave. The series covers the Ka-band spectrum, specifically targeting high-frequency applications. Variants within the series may differ by connector type or length, but share core electrical specifications. The D3I3841Q-2 represents a specific configuration within this product line.

RF Circulators And Isolators Replacement Considerations

D3I3841Q is a related variant with potentially different physical dimensions or connector tolerances. D3I3841-2 uses a Type-K female connector instead of Type-N. Verify mechanical fit and electrical continuity before substituting these parts.
