Abstract

A front-end module is provided. The front-end module includes a reception amplifier configured to amplify a received radio-frequency (RF) signal, first and second series switches configured to control a switching operation to electrically connect an output terminal of the reception amplifier and first and second reception ports to each other, a radio-frequency (RF) splitter configured to simultaneously transfer a received RF signal, amplified by the reception amplifier or bypassing the reception amplifier, to the first and second reception ports, first and second shunt switches configured to control a switching operation to electrically connect a ground and first and second branch nodes between the RF splitter and the first and second reception ports to each other, and first and second reflected wave removing impedance elements electrically connected between the first and second branch nodes and a ground.
