1. An electronic device comprising:
at least one communication processor configured to output at least one baseband signal;
a radio frequency integrated circuit (RFIC) configured to output at least one RF signal generated based on the at least one baseband signal;
at least one power amplifier configured to amplify the at least one RF signal and output amplified at least one RF signal to at least one antenna; and
at least one converter configured to provide a driving voltage for amplifying the at least one RF signal to the at least one power amplifier, wherein at least one capacitor is connected between the at least one converter and the at least one power amplifier,
wherein the at least one communication processor is configured to, based on no detection of an audible noise-associated event:
based on first association information between multiple driving voltages and multiple transmission powers of RF signals, identify at least one first driving voltage corresponding to at least one first transmission power of at least one first RF signal, wherein a minimum value of a driving voltage according to the first association information is a first voltage value, and
control a first converter corresponding to a first power amplifier among the at least one converter, so that the at least one first driving voltage is applied to the first power amplifier corresponding to the at least one first RF signal among the at least one power amplifier, wherein a peak-to-peak value of voltage applied to a first capacitor corresponding to the first power amplifier from among the at least one capacitor, while the at least one first driving voltage is applied is a first value,
based on detection of the audible noise-associated event:
based on second association information between multiple driving voltages and multiple transmission powers of RF signals, identify at least one second driving voltage corresponding to the at least one first transmission power of the at least one first RF signal, wherein a minimum value of a driving voltage according to the second association information is a second voltage value greater than the first voltage value, and
control the first converter so that the at least one second driving voltage is applied to the first power amplifier, wherein a peak-to-peak value of voltage applied to the first capacitor while the at least one second driving voltage is being applied is a second value less than the first value.
