A wireless communication device may include a processor, a first RF integrated circuit including a first control port for controlling a first RF processing circuit and a RF front end circuit and configured to communicate with the processor, a second RF integrated circuit including a second control port for controlling a second RF processing circuit and the RF front end circuit and configured to communicate with the processor, and the RF front end circuit controlled through the first control port and the second control port and configured to communicate with the first RF integrated circuit to exchange a first RF signal, wherein the processor is configured to determine whether to process a second RF signal in the second RF processing circuit and deactivate at least one component for processing the second RF signal in the second RF processing circuit based on the determining.

Wireless communication device including radio frequency integrated circuit and method of controlling the same

An electronic device may include a wireless communication circuit, a battery, a power management integrated circuit (PMIC) electrically connected to the wireless communication circuit and the battery and including a regulator, and a processor electrically connected to the wireless communication circuit, the battery, and the PMIC. The processor may, responsive to the electronic device satisfying a specified condition, identify a change in a magnitude of a voltage of an output terminal of the regulator for a first time interval, identify a ratio of a time interval during which the change in the magnitude of the voltage of the output terminal satisfies a threshold value with respect to the first time interval, and adjust the magnitude of the voltage of the output terminal in a step-wise manner based on the ratio.

Electronic device including a power management integrated circuit (PMIC) and operating method thereof

An electronic device including a substrate on which an electronic component is mounted according to various embodiments may include: a first electromagnetic interference (EMI) shield configured to shield the electronic component included in a first region of the substrate; and a second EMI shield supported by at least a part of the first EMI shield and configured to shield the electronic component included in a second region of the substrate.
