Tunable ferroelectric components in LTCC technology

Designs of a tunable matching network and a tunable phase shifter by LTCC ferroelectric technology are presented. The devices are designed for operation in K frequency band. Test structure measurements are presented along with extracted parameters of used ferroelectrics (dielectric permittivity and tunability). These measured parameters are then used to design phase-shifter and matching network using ADS "Momentum". Simulated performance of these components is presented.
