Piezoelectric Characteristics and Temperature Stability of Resonant Frequency of PbTiO 3 System Ceramics for High Frequency Resonator using S rd Overtone Thickness Vibration Mode

In this study, system ceramics with La molar ratio variation were manufactured for 24 MHz class resonator application. Electromechanical coupling factor, mechanical quality factor and dynamic range of overtone thickness vibration mode were measured as the variations of La and Nd molar ratio. Mechanical quality factor and dynamic range at
