QUARTZ CRYSTAL RESONATOR WITH IMPROVED TEMPERATURE PERFORMANCE AND METHOD THEREFOR

摘要

Quartz crystal resonators (30) with a first angle of rotation having an X-axis (17) and Z'-axis (19) lying within a plane corresponding to an AT-cut and a second angle of rotation (34) within the plane of the AT-cut and lying within a range of about +/-1 DEG to about +/-11.5 DEG from the Z'-axis of the AT-cut. The resonators include substantially opposing electrodes (36) disposed on major faces of the quartz crystal plate (32). The second angle of rotation (34) results in quartz crystal resonators (30) being produced with a more uniform distribution of temperature performances.
