Abstract
A module includes: a first duplexer including a common terminal coupled to a first terminal of a diplexer, the diplexer including an antenna terminal coupled to an antenna, the first terminal, and a second terminal; and a second duplexer including a common terminal coupled to the second terminal of the diplexer and having a passband different from a passband of the first duplexer, wherein a frequency at which a reactance component of an impedance is approximately zero and the impedance is less than a reference impedance is not located in a passband of the first duplexer, the impedance being an impedance when the second duplexer is viewed from a node at which the antenna terminal is divided into the first terminal and the second terminal in the diplexer.
