METHOD OF NARROW-TEMPERATURE MODE ACTIVITY DETERIORATION PREVENTION IN DOUBLE-MODE QUARTZ RESONATORS WITH PIEZO ELEMENTS OF FLAT-CONVEX AND CONVEX-CONVEX PROFILE Russian patent published in 2008 - IPC H03H9/19 H03H9/56 

FIELD: physics, radio.

SUBSTANCE: invention concerns radio electronics and can be applied in designing and manufacturing of double-mode quartz resonators, including the ones intended for highly stable quartz generators. The objective is achieved by using a method of narrow-temperature mode activity deterioration prevention in double-mode quartz resonators with piezo elements of flat-convex and convex-convex profile, involving a stage of applying an acoustic vibration absorber layer to piezo element surface outside the area of working mode vibration location.

EFFECT: prevention of narrow-temperature mode activity deterioration in double-mode quartz resonators with piezo elements of flat-convex and convex-convex profile.
