Title:
METHOD OF ADJUSTING APPLIED VOLTAGE FOR TRANSMISSION SIGNAL AMPLIFICATION AND ELECTRONIC DEVICE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/206482
Kind Code:
A1
Abstract:
According to one or more embodiments of the disclosure, an electronic device may include a power amplifier, a voltage generator, an antenna, and a communication processor. The CP determines whether an output waveform of the transmission signal which is output through the antenna is a first waveform or a second waveform. If the output waveform is the first waveform, the voltage generator generates a first output voltage for amplifying the first waveform by applying a first direct current (DC) power source of one or more first voltages. If the output waveform is the second waveform, the voltage generator generates a second output voltage for amplifying the second waveform by applying a second DC power source of a second voltage shifted by a designated level with respect to the first voltage, based on a peak power of the first waveform and a peak power of the second waveform.
