1. An electronic device comprising:
an antenna;
a communication circuit comprising:
a first amplifier configured to amplify a radio frequency signal to be transmitted through the antenna;
a first coupler connected to the first amplifier and configured to output a first amplifier output signal output from the first amplifier, to the antenna through a first port of the first coupler, and output at least a part of the first amplifier output signal to a first switch through a second port of the first coupler;
the first switch connected to the second port of the first coupler and configured to switch the at least a part of the first amplifier output signal, output from the second port of the first coupler, to a second amplifier or a second switch; and
the second amplifier configured to amplify the at least a part of the first amplifier output signal, output from the first switch; and
a processor 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.
