D3I1722S-2

RF Circulators And Isolators Overview

The D3I1722S-2 is an RF isolator manufactured by DiTom Microwave, designed for operation within the 1.7 GHz to 2.2 GHz frequency range. This component utilizes SMA female connectors and is housed in a module package. Key electrical specifications include a maximum average power rating of 10 W, an isolation level of 20 dB, a minimum insertion loss of 0.40 dB, and a maximum voltage standing wave ratio (VSWR) of 1.25. The device ensures signal directionality and protection in microwave circuits.

RF Circulators And Isolators Feature Summary

• Provides unidirectional signal transmission with high reverse isolation
• Operates effectively across the 1.7 GHz to 2.2 GHz bandwidth
• Features robust SMA female connector interfaces for reliable integration

RF Circulators And Isolators Applications

• Microwave communication systems requiring signal isolation
• Test and measurement equipment RF chains
• Transmitter output stages for reflected power protection

RF Circulators And Isolators Procurement Notes

Verify the specific suffix designation against official DiTom Microwave documentation to confirm exact performance tolerances and connector configurations. Ensure compatibility with system impedance requirements before procurement. Cross-reference part numbers with authorized distributors to obtain current availability and lead times. Confirm RoHS compliance status if required by project specifications.

RF Circulators And Isolators Selection Notes

Select this isolator when operating frequencies fall between 1.7 GHz and 2.2 GHz. Consider the 10 W average power limit and 20 dB isolation requirement for adequate system protection. The SMA female interface dictates mating cable or fixture compatibility. Evaluate VSWR and insertion loss impacts on overall link budget efficiency.

RF Circulators And Isolators Part Context

This component belongs to the DiTom Microwave D3I series of RF isolators. It shares the fundamental design architecture with variants like D3I1722N and D3I1720S-2, differing primarily in connector type and specific frequency band optimization. The series is engineered for general-purpose microwave isolation applications.

RF Circulators And Isolators Replacement Considerations

Direct substitutes may include D3I1722S or D3I1722N from DiTom Microwave, provided connector types match system requirements. Verify that alternative models meet identical frequency, power, and isolation specifications to ensure functional equivalence without redesign.
