Abstract
Disclosed is an electronic device including an antenna module comprising a plurality of radio frequency (RF) chains, and a processor configured to control the antenna module, wherein each of the RF chains comprises an amplifier that amplifies power and a power detector, and wherein the antenna module further comprises a switching circuit that selectively switches between a first path and a second path, the first path being a connection through which an RF signal converted in the antenna module is transmitted to the power detector causing the RF signal to be detected, and the second path being a connection through which the RF signal is transmitted to the amplifier causing the power detector to detect an RF signal of the amplifier.
