Superhigh Electromechanical Coupling and Zero-Temperature Characteristics of KNbO 3 and Wide Band Filter Applications

In this paper, a superhigh electromechanical coupling surface acoustic wave (SAW) propagating on a potassium niobate (KNbO 3 ) substrate is described and its applications for low-loss, wide band and temperature stable SAW filters are investigated. KNbO 3 has large piezoelectric constants. We obtaine...
