THE STUDY OF THE ISOLATION RATIO DEPENDENCE ON THE PARAMETERS OF THE ME ISOLATOR-ATTENUATOR FORMED ON A COPLANAR WAVEGUIDE
A review of the literature devoted to the investigation of ferrite isolators and circulators realized on a coplanar waveguide is performed. An electrically controlled magnetoelectric (ME) microwave isolator-attenuator based on layered ferrite-piezoelectric structure is considered. A formula for calculating the magnetic resonance line shift when an electric field is applied to the electrodes of the ME resonator is given. The results of a computer simulation study of the isolation ratio dependence on the length, thickness, and width of the ferrite film of the ME resonator are presented.
