Miniature Coaxial Isolators and Circulators

• April 03, 2023

A coaxial circulator is a passive, non-reciprocal three-port device that allows microwave or radio-frequency signal to exit through the port directly after the one it entered. An isolator is a two-port device that transmits microwave or radio frequency power in one direction only, while the other direction is blocked. Isolators can be considered as a special case of circulators and are made by suitably terminating one port of the circulator ports.
