Abstract: Various embodiments of the disclosure relate to a device and a method for supplying power to a plurality of power amplifiers in an electronic device. An electronic device may include: a first power amplifier, a second power amplifier, a third power amplifier, a first power supply module including a power supply configured to supply power to the first power amplifier or the second power amplifier, a second power supply module including a power supply configured to supply power to the second power amplifier or the third power amplifier, and a detection module comprising circuitry configured to identify a state of a connection between the second power amplifier and the first power supply module and a state of a connection between the second power amplifier and the second power supply module, wherein the detection module may be configured to output a power control signal based on detecting that the second power amplifier is connected to the first power supply module and the second power supply module, wherein power supply to the second power amplifier from the first power supply module or the second power supply module may be shut off based on the power control signal of the detection module.
