1. An electronic device comprising:
a communication processor;
a radio frequency (RF) integrated circuit (RFIC) configured to receive a signal output from the communication processor and to modulate the signal into an RF signal;
a power management circuit;
a first power amplifier configured to receive power supplied from the power management circuit;
a second power amplifier connected in parallel to the first power amplifier and configured to receive the power supplied from the power management circuit;
at least one capacitor connected in parallel to a power supply terminal of the first power amplifier; and
at least one switch connected between the power supply terminal and the at least one capacitor,
wherein the communication processor is configured to:
identify a power amplification mode based on a frequency band of the RF signal,
wherein the at least one switch is configured to control electrical connection or disconnection between the power supply terminal and the at least one capacitor based on the identified power amplification mode, and
wherein based on the power amplification mode, the RF signal is amplified via either one of the first power amplifier or the second power amplifier.
