Low-loss, highly tunable microwave devices are fabricated using composite structures in which effective dielectric constant is controlled by piezoelectric induced changes in the energy distribution within the devices. With this new approach, high degree of tunability is possible while utilizing high Q dielectrics. Highly tunable (more than 20) microstrip and ring resonators, and wide-band low-loss phase shifters are realized experimentally.
