Abstract
A tunable isolator using the coupled microstrip line is proposed. The tunability is obtained by varying the applied angle of the DC bias magnetic field at the YIG film. The nonreciprocal coupling between the two microstrip lines on a ferrite substrate can be used to create an isolation mechanism. A frequency tunable isolator is designed for use at the microwave frequency band.
