Faraday Isolators
Mi-Wave’s 115 series isolators use the Faraday principle of rotation in a broadband dielectric waveguide design to achieve high isolation across full waveguide bands. These faraday isolators are available in standard waveguide sizes from 18.0 to 325 GHz
See specific bands below with datasheets, outlines & plots available.

Faraday Isolators
An isolator is a two-port device that transmits microwave or radio frequency power in one direction only. Due to internal behavior, the propagation in one direction is allowed while the other direction is blocked. The non-reciprocity observed in these devices usually comes from the interaction between the propagating wave and the material, which can be different with respect to the direction of propagation.
