A newly composite quartz crystal resonator

Here a kind of newly designed quartz crystal resonator suit for space application is presented. It is designed and fabricated in China for the first time. Generally, electrical connection is made to the quartz resonator electrodes by electrically conductive adhesive. The electrical connection to this kind of newly designed quartz crystal is completed by welding gold germanium or gold stanuum alloy. The resonator has advantages such as long lifetime, reliability, etc. The externality belongs to the routine series of HC/49U,HC/43U,TO-5,TO-8.It will be widely used in many fields, for example, spaceflight, military, etc.
