  • Abstract
    The aim of investigations of barium-strontium titanate solid solution BaxSr1-xTiO3 BSTO films and ceramic layers is a realization of tunable components for microwave tunable filters and microwave tunable phase shifters for steerable antenna arrays. The experiment with a tunable resonator on a strontium titanate (STO) single crystal is also discussed. The conducting plates of the resonator are performed from YBCO epitaxial films. The high-temperature superconductors (HTS) plates make possible to apply the biasing voltage to the (STO) resonator. The dielectric response of ferroelectric materials strongly depends on temperature. In this connection, one of the intriguing characteristics of the ferroelectric tunable devices is the range of operational temperature.
