IMPROVED FREQUENCY-TEMPERATURE CHARACTERISTICS OF QUARTZ CRYSTAL UNITS.
Abstract
Two different methods for the temperature compensation of an AT type quartz resonator by means of stresses applied to the crystal plate were explored. The first method employs compressional and extensional stresses in the Z' direction. The second method utilizes a flexural strain about the X-axis. Compensated resonators of both types were fabricated and tested. These exhibit improved frequency stability as compared to uncompensated resonators, but the goal of 1 part per million has not been achieved over the entire -40 to +80 C range. (Author)
