D4I1722S

RF Circulators And Isolators Overview

The D4I1722S is an RF isolator manufactured by DiTom Microwave, designed for operation within the 1.7 GHz to 2.0 GHz frequency range. It features SMA-FEMALE connectors and a module package configuration. The component supports an average forward power of 150 W, providing 40 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.

RF Circulators And Isolators Feature Summary

• Provides signal isolation in the 1.7 to 2.0 GHz band
• Supports high average forward power handling
• Utilizes SMA-FEMALE connector interface

RF Circulators And Isolators Applications

• RF signal transmission systems
• Microwave communication equipment
• Test and measurement instrumentation

RF Circulators And Isolators Procurement Notes

Verify the specific suffix against official documentation, as variants such as D4I1722S-3 exist with identical core specifications but distinct ordering identifiers. Confirm that the required SMA-FEMALE connector type matches the system interface requirements. Ensure the 150 W power rating and 40 dB isolation meet the design constraints. Check RoHS3 compliance status if environmental regulations apply to the final assembly.

RF Circulators And Isolators Selection Notes

Select this model when a 1.7 to 2.0 GHz operating range is required. The 150 W power capacity suits moderate-to-high power applications. The 0.8 dB insertion loss and 1.25 VSWR indicate standard performance levels. Compare against the D3I1722S if a wider 1.7 to 2.2 GHz bandwidth is necessary, noting its lower 0.4 dB insertion loss. Ensure the SMA-FEMALE interface aligns with existing cabling infrastructure.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave D4I1722 series of connectorized ferrite isolators. The series covers frequencies from 400 MHz to 43.5 GHz. The D4I1722S specifically targets the 1.7 to 2.0 GHz segment. It shares the module form factor with other series members but differs in connector type and electrical parameters based on the specific suffix designation.

RF Circulators And Isolators Replacement Considerations

The D4I1722S-1 is a confirmed variant within the same product family. It maintains the 1.7 to 2.0 GHz frequency range and isolator function. Verify if the suffix change impacts mechanical or electrical tolerances before substitution.
