Piezoelectric filter using LiTaO3 substrate

摘要: A multi-mode piezoelectric filter includes a substrate made of LiTaO3 single crystal, plurality spaced electrodes which are formed adjacently on front major surface the substrate, and counter electrode is rear in opposition to electrodes. The coact with intervening portion form two or more energy trapped type elements vibrating thickness shear mode such that coupled cascade connection. Damping material as silicone gel applied at least elements.
