Tunable microwave devices based on bulk and thin film ferroelectrics
Artikel i vetenskaplig tidskrift, 1998

Electrically tunable microwave resonators and filters based on bulk single crystal SrTiO3 and KTaO3 with superconducting plates are presented and discussed. Filters are designed for operation at frequencies 0.2 – 2.0 GHz. Thin film varactors and phase shifters, designed for cryogenic or room temperature operation and based on epitaxial SrTiO3 and BaSrTiO3 are also discussed. The frequency band for the thin film devices is 0.5 - 40 GHz.
