Tactical BVA quartz resonator performance

The author considers the performance of tactical BVA quartz resonators, specifically their measured frequency stability. Data are presented demonstrating the resonators' ability to survive harsh environmental conditions. Test results suggest that an oscillator using a tactical BVA resonator could be developed that would have very high frequency stability, be relatively small, and have low mass. The tactical resonators evaluated are 10-MHz, third overtone, SC (stress-compensated) cut devices housed in HC-40 enclosures. The Q of the resonators tested was between 1.2 and 1.3 million.<>
