Reliable quadratic for frequency-turnover temperature vs orientation of rotated Y-cut quartz plate resonator oscillating in c-mode

This paper describes the reliable quadratic for frequency-turnover temperature vs orientation of c-mode in the temperature range -196-300/spl deg/C. From the relation we can show the useful piezoelectric cuts of quartz for the resonator and sensor at the elevated temperature region. In particular, the experiments are carried out in the vicinity of AT-cut.<
