Cryogenic isolators operate at cryogenic temperatures at or below 77K

East Coast Microwave, a subsidiary of Powell Electronics and supplier of connectors and more for high-rel applications including defence, aerospace and industrial, now provide cryogenic isolators from DiTom Microwave.

These three-port ferrite devices are intended to operate at cryogenic temperatures at or below 77K and deliver high isolation in one direction while supplying low loss in the other direction. Cryogenic isolators are excellent for usage in laboratories, quantum computing, and aerospace applications.

The D3I4080Y cryogenic isolator, for example, operates from 4GHz to 8 GHz. It can handle an average forward input power of up to 30W, a peak input power of 50W, and a reverse input power of 2W. The component offers more than 16dB of isolation and has an insertion loss of lower than 0.4dB. It is provided in a module that measures 1" x 1" x 0.5" and features SMA (male/female) connectors.
