Abstract: An electronic device may comprise antenna, low-noise amplifier, radio frequency integrated circuit (RFIC), and communication. The communication processor may be configured to identify a low-noise amplifier for amplifying a first RF signal and a low-noise amplifier for amplifying a second RF signal, based on the low-noise amplifier for amplifying the first RF signal differing from the low-noise amplifier for amplifying the second RF signal, set a first gain of the low-noise amplifier for amplifying the first RF signal, set a second gain of the low-noise amplifier for amplifying the second RF signal, based on the low-noise amplifier for amplifying the first RF signal being identical to the low-noise amplifier for amplifying the second RF signal, set a third gain of a low-noise amplifier of amplifying the first RF signal and the second RF signal.

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.
