Abstract: An electronic device may include: at least one communication processor, an RFIC, at least one power amplifier, and at least one converter and wherein the at least one communication processor is configured to: set a driving voltage, to be applied to a first power amplifier for amplifying a first RF signal provided from the RFIC among the at least one power amplifier, to be a first voltage, based on an APT mode, control at least part of the at least one converter to provide a first voltage, set based on the APT mode, to the first power amplifier during a transmission period of the first RF signal, and control at least part of the at least one converter to provide the first voltage to the first power amplifier during at least partial period of a remaining period in which no RF signal is transmitted, based on the occurrence of an event associated with audible noise.
