Cut angles for quartz crystal resonators
Abstract
The present invention concerns itself with crystallographically doubly rotated quartz orientations vibrating in the transverse c-mode with turnover temperatures which are considerably less sensitive to angular misorientation than the comparable well known AT- or BT-cuts. These crystals are arbitrarily designated as AK-cut crystals and are defined by phi-angle variations between 30 deg.-60 deg, and theta-angle variations between 12 deg.-32 deg. The turnover temperatures of these resonators are between 60 deg. C and 200 deg. C.
