Abstract: An electronic device is provided. The electronic device includes a first antenna and a second antenna. The electronic device includes power supply circuitry. The electronic device includes a first front end module (FEM) including a switch, a power amplifier (PA) connected to the power supply circuitry through the switch to obtain a transmit (Tx) power of a first wireless signal transmitted through the first antenna based on a voltage from the power supply circuitry, and a control circuitry. The electronic device includes a second FEM including a PA connected to the power supply circuitry to obtain a Tx power of a second wireless signal transmitted through the second antenna based on the voltage from the power supply circuitry. The control circuitry is configured to obtain a signal indicating whether the PA in the first FEM connected to the power supply circuitry through the switch is at least partially damaged. The control circuitry is configured to control the switch to disconnect the power supply circuitry from the PA in the first FEM, in response to the signal indicating that the PA in the first FEM is at least partially damaged.
