ABSTRACT:
The invention relates to piezoelectric resonators. An interposer element is used between a resonating plate and the resonator package to provide improved (i.e. reduced) acceleration sensitivity. The interposer element is preferably of similar thermal expansion characteristics to the resonating plate. Electrical connection to the resonating plate from the exterior of the package is preferably provided via the interposer element.
