    Abstract: Disclosed are a method for controlling a voltage supplied to a radio frequency (RF) transmission/reception module, and an electronic device for carrying out same. The electronic device, according to an embodiment, comprises: a communication processor including at least one processor comprising processing circuitry; an RF integrated circuit configured to generate a RF signal by processing data received from the communication processor, and transmit the RF signal to a RF transmission/reception module; the RF transmission/reception module comprising an amplification circuit configured to amplify the RF signal, and an overvoltage protection circuit configured to reduce overvoltage-induced damage to the amplification circuit, and configured to transmit the amplified RF signal; and a power management integrated circuit configured to manage power supplied to the amplification circuit using a voltage converter comprising a boost circuit configured to step up a voltage input into the boost circuit and a buck circuit configured to step down a voltage input into the buck circuit, wherein at least one processor of the communication processor, individually and/or collectively, is configured to: use the overvoltage protection circuit to detect the occurrence of an overshoot in which a voltage supplied to the RF transmission/reception module exceeds a threshold value, and in response to detecting the occurrence of the overshoot, control the power management integrated circuit and thus reduce an operation time of the boost circuit.

    Abstract: An electronic device includes a battery, a plurality of capacitors, a converter that receives power from the battery and charges each of the plurality of capacitors to different voltages based on the power, a plurality of switches that switch a first path and a second path of each of the plurality of capacitors, and a controller. The controller selects a first switch among the plurality of switches based on a received signal, and controls the first switch such that a path of a capacitor connected to the first switch is switched from the first path to the second path, and the first path is a path which electrically connects each of the plurality of capacitors to the converter, the second path is a path which electrically connects each of the plurality of capacitors and a power amplifier (PA).

    Abstract: According to an embodiment, an electronic device may comprise: memory storing instructions and at least one processor, comprising processing circuitry, individually and/or collectively. The instructions, when executed by at least one processor, cause the electronic device to: identify a position of the electronic device and at least one satellite from a GPS signal based on identifying a first event, identify whether a value based on a relative angle between a trajectory axis corresponding to the at least one satellite and the electronic device meets a first condition, identify whether a value based on a relative distance between the electronic device and the at least one satellite meets a second condition based on identifying that the value based on the relative angle does not meet the first condition, set a first power lower than a third power to a transmission power of a transmission signal corresponding to satellite communication based on identifying that the value based on the relative distance meets the second condition, and set a third power to a transmission power of a transmission signal corresponding to satellite communication based on identifying that the value based on the relative distance does not meet the second condition.
