    Abstract: According to an embodiment, an electronic device may comprise: memory storing instructions, a first power amplifier (PA) selectively connected to at least one of a plurality of modulators through a first switch, a first modulator including a second switch connected between the first switch and a first capacitor and a third switch connected to an output end of a first buck converter and being among the plurality of modulators configured to selectively operate in an envelope tracking (ET) mode or an average power tracking (APT) mode, a second modulator including a fourth switch connected between the first switch and a second capacitor and a fifth switch connected to an output end of a second buck converter and being among the plurality of modulators configured to selectively operate in the ET mode or the APT mode, and at least one processor, comprising processing circuitry, operatively connected to the first PA, the first modulator, and the second modulator. The instructions, when executed by at least one processor, individually and/or collectively, may cause the electronic device to: control the first modulator to operate in the APT mode based on identifying a first event associated with network communication, control the first switch to connect the first PA to the first modulator and the second modulator; control the second switch, the third switch, and the fourth switch to turn on; and control the fifth switch to turn off based on the first modulator operating in the APT mode.

    Abstract: An electronic device is provided. The electronic device includes an antenna, a transmission path electrically connected to the antenna and including at least one amplifier, a transceiver connected to the transmission path and converting a signal, a feedback path connected between the transmission path and the transceiver, at least one processor connected to the transceiver and communicating with at least one external electronic device by using the transceiver, and a memory connected to the at least one processor. The processor may obtain first information about a first phase and a first magnitude, which are associated with the first frequency, and second information about a second phase and a second magnitude, which are associated with a multiplied frequency of the first frequency, from the transmission signal and the reflection signal using the transceiver, and may determine a state of the electronic device based on the first information and the second information.
