Abstract
A device includes a plurality of electrode actuated acoustic resonators coupled to form complementary paths to operate as a filter. Each acoustic resonator has an electrical input and an electrical output that contributes to a static capacitance. A compensation impedance is coupled to at least one of the paths to reduce adverse effects from the static capacitances of the acoustic resonators.
