Electronic device including a plurality of power amplifiers and operating method thereof

An electronic device comprising:

• at least one antenna;
• a communication processor;
• and
• a wireless communication circuit configured to be electrically connected to the at least one antenna and the communication processor,
• wherein the wireless communication circuit comprises
• a first power amplifier configured to amplify a first signal provided from the communication processor and to output the first signal to the at least one antenna,
• a second power amplifier to amplify a second signal provided from the communication processor and to output the second signal to the at least one antenna,
• a third power amplifier to amplify a third signal provided from the communication processor and to output the third signal to the at least one antenna,
• 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 is 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, and
• wherein power supply to the second power amplifier from the first power supply module or the second power supply module is shut off based on the power control signal of the detection module.
