Abstract
A two-pole monolithic piezoelectric filter (50) provides an improved frequency response at specified frequencies above the center frequency of a two-pole filter; at these frequencies the frequency response exceeds the attenuation of a four-pole filter without any increase in space, volume, or cost by the inclusion of additional resonator stages (64 and 68) formed into the substrate (52). Appropriate selection of the dimensions of these resonator stages can be used to adjust the frequency at which these resonator stages provide additional desired attenuation.
