Abstract

Abstract A mounting structure for one or more coupled resonator crystal plates with each plate having a number of electrodes, and pairs of the electrodes forming a resonant structure, includes a conductive frame member having portions which are secured to one of the electrodes from separate pairs of electrodes. A number of mounting means are each connected to separate ones of the other electrodes of the pairs of electrodes. The mounting members have a bend formed therein for resiliently supporting the crystal plates and allowing expansion and contraction of the crystal plates with temperature variations. The frame member and mounting members are secured in a mounting base with portions extending through the mounting base for connection to external circuitry.
