Abstract
A piezoelectric resonator (100) with an attenuated spurious response. The resonator (100) includes a piezoelectric crystal plate (102) having opposite surfaces (104, 106), electrodeS (108, 114) positioned in overlying relationship on each of the opposite surfaces (104, 106), the electrodes (108, 114) being substantially coextensive and opposite, and providing a primary frequency mode of operation and spurious modes upon suitable energization, and the electrodes (108, 114) having a grid-like structure (124) to provide a substantially uniform distribution of electrical charges over an electroded region (126).
