Abstract
A multiplexer includes a common terminal, a first reception output terminal, a second reception output terminal, a first filter that is connected between the common terminal and the first reception output terminal, a second filter that is connected between the common terminal and the second reception output terminal and that has a passband different from that of the first filter, and an impedance matching circuit that is disposed between the common terminal and the second filter. The impedance matching circuit includes a serial arm resonator disposed in series on a path connecting the common terminal to the second filter.
