Abstract

A high frequency circuit includes a first demultiplexing circuit including a first high pass filter and a low pass filter and a second demultiplexing circuit including a band elimination filter and a band pass filter, the second demultiplexing circuit being connected in series with the first demultiplexing circuit. At least one of the band elimination filter and the band pass filter includes an elastic wave resonator. An attenuation band of the band elimination filter and a pass band of the band pass filter is located between a pass band of the first high pass filter and a pass band of the low pass filter.
