QUARTZ RESONATOR Russian patent published in 2008 - IPC H03H9/19 

FIELD: radio engineering.

SUBSTANCE: quartz resonator includes quartz piezo-element with electrodes located in operating volume of quartz resonator and lid. Operating volume is formed by dielectric basis with surfaces covered with electroconductive coating. Electroconductive coating of dielectric basis is divided into two electrically isolated parts and connected with piezo-element electrodes. Quartz piezo-element is fixed by means of current-conducting paste on conducting film. Piezo-element is fixed in electrode outputs so that electrode outputs are electrically connected with electrically isolated parts of film coating. Gap is available between active part of piezo-element and film coating. Gap volume is equal to current-conducting paste thickness which is under piezo-element in fixing points. Quartz resonator lid is strengthened by means of low-melt glass enamel.

EFFECT: reduction of size and weight and long-term stability of quartz resonator frequency.
