D3I5771

RF Circulators And Isolators Overview

The D3I5771 is a single junction coaxial ferrite isolator manufactured by DiTom Microwave. It operates within a frequency range of 5.7 GHz to 7.1 GHz. The device features SMA female connectors on all ports and is housed in a module package measuring 0.62 inches by 0.5 inches by 0.78 inches. Key electrical specifications include an insertion loss of 0.5 dB, a voltage standing wave ratio (VSWR) of 1.3, and an isolation level of 18 dB. It supports an average forward power of 20 W and functions reliably between -30°C and +65°C.

RF Circulators And Isolators Feature Summary

RF Circulators And Isolators Procurement Notes

Verify the specific part number suffix when ordering, as variations such as D3I5771-1 exist with identical core specifications but potentially different packaging or minor configuration details. Confirm connector type compatibility with system interfaces. Check current availability status as supply may be limited or subject to manufacturer lead times. Ensure environmental ratings meet operational temperature requirements for the intended deployment scenario.

RF Circulators And Isolators Selection Notes

Select this component for applications requiring isolation within the 5.7 to 7.1 GHz band. Consider the 20 W power rating and 18 dB isolation performance against system requirements. Evaluate the SMA female interface for connection compatibility. Compare physical dimensions against available space constraints. Review thermal management needs given the specified operating temperature range.
