AI Technical Summary
Existing quartz crystal oscillators cannot maintain high precision within a working temperature range of -65℃ to +200℃, which cannot meet the needs of special fields such as lunar surface exploration and deep Earth exploration.
A quartz crystal wafer resistant to 200℃ ultra-high temperature is cut and positioned using a special spatial orientation, and a suitable oscillation circuit is designed. Combined with a multi-layer base structure and a high-frequency current parallel sealing method to form a sealed environment, the quartz crystal oscillator can operate normally in the range of -65℃ to +200℃.
It achieves high precision and high stability of quartz crystal oscillators over a wide temperature range, expands the operating temperature range to meet the needs of more fields, and has good parameter consistency without increasing cost.
