Abstract
An acoustic wave filter includes a filter circuit connected to input-and-output terminals, and a canceling circuit connected in parallel to at least a portion of a first path connecting the input-and-output terminals. The filter circuit includes one or more series-arm resonators on the first path, and one or more parallel-arm resonators between the first path and a ground. The canceling circuit includes acoustic wave resonators in parallel or substantially in parallel in a propagation direction of an acoustic wave. At least one of the acoustic wave resonators is connected to the ground, and an anti-resonant frequency of the at least one of the acoustic wave resonators is in a pass band of the filter circuit.
