High-frequency module and communication device

摘要

A high-frequency module includes first and second demultiplexers and a band elimination filter. The first and second demultiplexers include common terminals, transmission filters, and reception filters, respectively. In the band elimination filter, a demultiplexer-side terminal is connected to the common terminal of the first demultiplexer. The band elimination filter includes a first pass band, and a second pass band and a stop band that are located adjacent to each other within the first pass band. The band elimination filter is configured so that the second pass band includes the pass band of each of the transmission filter and the reception filter in the first demultiplexer and the stop band includes the pass band of the transmission filter in the second demultiplexer.
