Electrically-tunable microwave phase shifter based on ferrite-piezoelectric layered structure

Abstract

A new class of electrically tunable microwave signal processing devices based on layered ferrite-piezoelectric structure is proposed. A trilayer magnetoelectric structure consisting of a lead magnesium niobate-lead titanate (PMN-PT) and yttrium iron garnet (YIG) film on gadolinium gallium garnet (GGG) substrate is considered. Design and experimental data of microstrip phase shifter are presented.
