Abstract

A multiplexer includes a common terminal, an inductor including a first end connected to the common terminal and a second end, a filter connected to the second end and having a first pass band, a filter connected to the common terminal and having a second pass band located on a higher frequency side relative to the first pass band, an inductor connected between a ground and a path that links the second end to the filter, and a capacitor connected between the path and the ground. A resonant frequency of an LC parallel resonance circuit including the inductor and the capacitor is located between the first pass band and the second pass band.
