Abstract

An extractor includes a band pass filter and a band elimination filter. One filter of the band pass filter and the band elimination filter includes at least one serial arm resonator and at least one parallel arm resonator that are each defined by an acoustic wave resonator. Any one of the at least one serial arm resonator and the at least one parallel arm resonator includes, among a divided resonator group divided resonator including a plurality of divided resonators coupled in series to each other, a first divided resonator group that is a largest in number of the divided resonators coupled in series and a smallest in capacitance.
