The amplifier includes: an amplifying unit amplifying and transferring a transmission target signal to a TDD switch; the TDD switch transferring a signal received from the amplifying unit to a filter unit when the amplifier operates in a TDD mode, and transferring a signal received from the filter unit to a duplex mode selection switch; the duplex mode selection switch transferring a signal received from the filter unit to a receiving side; and a controller controlling the duplex mode selection switch to transfer the signal received from the filter unit to the receiving side without passing through the TDD switch when the received duplex mode selection signal is a FDD mode selection signal.
