Traditional crystal filters are characterized with small passband ripple, large stopband attenuation and low shape factor. However, their applicatin and popularization are limited by their deficiency in volume and vibration resistance. In order to meet the needs of miniaturization of aerospace electronic devices, the 16.25MHz minitype anti-vibration monolithic crystal filter is developed. The main...Show More
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 popularization. This paper introduces a small BVA quartz resonator. By optimizing the internal structure and processing technology, the size of small BVA quartz resonator can be reduced to HC-40/U and the anti-vibration level reaches 15grams. At t...Show More
