M. Takeuchi et al., RELIABLE FREQUENCY TEMPERATURE CHARACTERISTICS OF THE NEW QUARTZ-CRYSTAL RESONATORS VIBRATING IN THICKNESS-SHEAR MODES, Sensors and actuators. A, Physical, 40(2), 1994, pp. 97-101
This paper describes the turning points of frequency-temperature chara
cteristics for rotated Y-cut quartz-crystal resonators vibrating in b
modes in the temperature range 0-300-degrees-C. In the high-temperatur
e region, the new experimental results are compared with the theoretic
al values calculated by use of the idealized thickness-vibration theor
y.
