Abstract
Bandpass filters and methods of designing bandpass filters are disclosed. A bandpass filter includes a plurality of series acoustic resonators connected in series between an input and an output, and a plurality of\ shunt acoustic resonators, each shunt acoustic resonator connected between a ground and one of the input, the output, and a junction between two of the plurality of series acoustic resonators. A first shunt resonator of the plurality of shunt resonators has a motional resonance frequency higher than and adjacent to an upper edge of a passband of the bandpass filter.
