Abstract: An apparatus and method for applying digital pre-distortion (DPD) technology in an electronic device which uses an envelope tracking (ET) method is provided. The electronic device includes an antenna, a modem, a transceiver configured to convert a signal generated in the modem into a radio frequency signal, an ET modulator configured to supply power to a power amplifier based on an amplitude component of the signal generated in the modem, and the power amplifier configured to amplify power of a signal received from the transceiver based on an output signal of the ET modulator. The modem generates a signal by using a DPD) variable corresponding to output impedance of the power amplifier caused by the antenna from among a plurality of DPD variables.
