High-Q, Stress-Compensated Crystal Device.
Abstract
A doubly rotated, stress and temperature compensated quartz crystal resonator. The crystal cuts are arbitrarily designated the SK1 and SK2 cuts. Lateral field excitation is used to excite only the b-mode of vibration (fast quasi-shear) and suppress the c mode (slow quasi-shear). Exclusive excitation of the b mode produces a resonator with a higher Q and lower phase noise than otherwise achievable. (Patent application)
