Abstract: A piezoelectric resonator (10) with an attenuated spurious response. The resonator (10) includes a piezoelectric crystal plate (12) having opposite surfaces (14, 16), an electrode (18, 24) positioned in overlying relationship on each of the opposite surfaces (14, 16), the electrodes (18, 24) being substantially coextensive and opposite, and providing a primary frequency mode of operation and spurious modes upon suitable energization, and a number of mass loading structures (34) on at least one of the surfaces (14, 16) substantially surrounding at least one of the electrodes (18, 24).
