Abstract
An acoustic wave filter includes: a plurality of first series resonators connected in series between a first port and a second port; a plurality of shunt resonators, each shunt resonators being connected between a different node disposed between the first port and the second port and the ground; at least one second series resonator connected in parallel to at least one of the first series resonators; and an inductor connected between one of the shunt resonators and the ground. A resonant frequency of the shunt resonator connected to the inductor is the same as a resonant frequency of at least one of the plurality of first series resonators.
