    Abstract: An electronic device includes an antenna, a communication circuit, and a processor. The communication circuit includes a first amplifier configured to amplify a radio frequency signal; a first coupler configured to output a first amplifier output signal output from the first amplifier, to the antenna through a first port, and output at least a part of the first amplifier output signal to a first switch through a second port; and a second amplifier configured to amplify the second portion of the first amplifier output signal, output from the first switch. The processor is operably connected to the antenna and the communication circuit, wherein the processor is configured to, based on a magnitude of the first amplifier output signal, control the first switch and the second switch to use the first amplifier, or to use the first amplifier and the second amplifier.
