DHC1722-1

RF Circulators And Isolators Overview

The DHC1722-1 is an active RF circulator manufactured by DiTom Microwave, designed for the K-band frequency range of 17.3 GHz to 22.00 GHz. It features Type-K female connectors and operates in a module package configuration. The component supports an average forward power of 10 W with a minimum isolation of 20 dB and a voltage standing wave ratio (VSWR) of 1.25.

RF Circulators And Isolators Feature Summary

• Provides non-reciprocal signal routing within the specified microwave frequency band
• Ensures high isolation between ports to prevent signal reflection
• Maintains low insertion loss for efficient power transmission

RF Circulators And Isolators Applications

• Spacecraft communication systems
• Defense radar transponders
• Satellite ground station uplinks

RF Circulators And Isolators Procurement Notes

Verify the specific connector interface and power rating against system requirements before ordering. Confirm RoHS3 compliance and environmental testing standards if used in aerospace applications. Check manufacturer documentation for precise mechanical dimensions and thermal management guidelines to ensure proper integration into the final assembly.

RF Circulators And Isolators Selection Notes

Select this model when a K-band circulator with Type-K female interfaces is required. Ensure the operating frequency aligns with the 17.3–22.00 GHz range. Consider the 10 W average power handling capability relative to the application's peak and continuous wave power levels. Verify that the 20 dB minimum isolation meets the system's noise floor and interference rejection specifications.

RF Circulators And Isolators Part Context

DiTom Microwave specializes in ferrite isolators and circulators for space and defense markets, holding AS9100 Rev C certification. The company provides both commercial-off-the-shelf and high-reliability products ranging from 400 MHz to 40 GHz, often supplying hardware qualified for satellite manufacturing and thermal vacuum environments.

RF Circulators And Isolators Replacement Considerations

The D3I1822-1 is an isolator variant from the same manufacturer covering a similar frequency range but serves a different function. Direct functional substitutes require matching circulator specifications including frequency, power, and connector type.
