Abstract :
The investigation results of piezoelectric BAW resonators using single crystals of strong piezoelectrics are given. The possibility of face shear mode excitation in lithium tantalate piezoelectric elements of single-rotated cuts is reported which enables manufacturing resonators with zero frequency-temperature coefficients. The information regarding resonance spacing value of the resonator versus operating mode of vibration and the frequency range used is included. The realizable parameters of resonator types using lithium tantalate and La3Ga5SiO14 (LGS) are also given
