Abstract

An electronic device supporting beamforming and a method of operating the electronic device are provided. The electronic device includes a first amplifier configured to amplify a first signal and a second amplifier for amplifying a second signal, a power control module configured to generate first power control information based at least on a first attribute of the first signal and generate second power control information based at least on the first power control information and a second attribute of the second signal, and at least one power supply module configured to control power supplied to the first amplifier based at least on the first power control information and control power supplied to the second amplifier based at least on the second power control information.
