ABSTRACT:
A resonator assembly comprises a rigid support and a rigid crystal which are rigidly connected along linear segments which have one or more matched thermal characteristics. In a particular embodiment, a thermally matched resonator assembly comprises a Z-cut quartz crystal support, a quartz crystal resonator having an active region and including a crystalline structure oriented relative to X-, Y- and Z-crystallographic axes, which X- and Y-crystallographic axes define an X-Y crystallographic plane; and a rigid connector structure for rigidly connecting the resonator to the support along a segment of a line of a plane parallel to or including the X-Y crystallographic plane, which segment extends across a surface of the resonator and is spaced from the center of the active region of the resonator. A method of mounting a crystal which has the aforementioned crystalline structure to a Z-cut quartz support comprises: selecting a chord on a face of the crystal, which chord is a segment of a line of an X-Y plane intersecting the face of the crystal away from the center of an active region of the crystal; and bonding the crystal of the Z-cut quartz support along the length of the chord.
