Abstract: Traditional BVA quartz resonator has the characteristics of low aging and high Q, but the weakness in size and anti-vibration limits its application and dissemination. This paper introduces a new BVA quartz resonator. By optimizing the structure design of the capacitor chip and the quartz blank, the smaller size of the quartz crystal chip and the capacitor chip is developed. The size of small BVA quartz resonator can be reduced to HC-40/U and the anti-vibration level has been improved. At the same time, its other performance is comparable to traditional BVA quartz resonator.
