D4I9211

RF Circulators And Isolators Overview

The D4I9211 is a single-port RF isolator manufactured by DiTom Microwave, designed for operation within the 9.2 GHz to 10.5 GHz frequency range. It features SMA female connectors and supports an average forward power of 10 W. Key electrical specifications include a minimum isolation of 46 dB, insertion loss of 0.6 dB, and a voltage standing wave ratio (VSWR) of 1.2. The device operates between -30°C and +65°C, with physical dimensions of 1 in x 0.5 in x 0.7 in.

RF Circulators And Isolators Feature Summary

• Provides high isolation performance of 46 dB to protect source components from reflected signals
• Supports continuous average forward power handling up to 10 W for robust signal transmission
• Maintains low insertion loss of 0.6 dB to minimize signal attenuation in the pass band

RF Circulators And Isolators Applications

• RF source protection in microwave communication systems
• Signal integrity enhancement in radar transmitters
• Component isolation in satellite ground station equipment

RF Circulators And Isolators Procurement Notes

Verify connector configuration compatibility, as the series includes variants with SMA male or other interface types. Confirm RoHS compliance status through official documentation prior to integration. Ensure thermal management aligns with the specified operating temperature range of -30°C to +65°C. Check manufacturer availability for lead time estimation, as distribution channels may vary.

RF Circulators And Isolators Selection Notes

Select this model when precise isolation is required in the Ku-band frequency spectrum. Consider the 10 W power rating against system peak loads to prevent damage. Evaluate the SMA female interface against existing board layouts. Compare VSWR metrics with system requirements to ensure impedance matching efficiency.

RF Circulators And Isolators Part Context
