Abstract
Provided is an electronic device that includes a communication processor; a transceiver electrically connected to the communication processor; a first power amplifier electrically connected to the transceiver; a first antenna electrically connected to the first power amplifier; and a first supply adjustor electrically connected to the communication processor and the first power amplifier. The communication processor can be set to perform a first determination about whether a carrier bandwidth part of a first signal transmitted through the first antenna exceeds a first threshold value, perform a second determination about whether the power of the first signal exceeds a second threshold value, select a first tracking mode as an envelope tracking mode or an average power tracking mode on the basis of at least a portion of the first determination and the second determination, and control the first supply adjustor using the selected first tracking mode.
