Abstract
A high frequency module includes a duplexer that includes a transmission filter, a receive-only filter, and a power amplifier that power-amplifies a transmission signal. In order to improve the isolation characteristics between a transmission signal and a reception signal at the duplexer, the receive-only filter is arranged between the power amplifier and the duplexer.
