Title:
ELECTRONIC DEVICE FOR CONTROLLING WIRELESS TRANSMISSION, AND OPERATING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/171885
Kind Code:
A1
Abstract:
Disclosed is an electronic device comprising: an antenna; a power amplifier (PA) for transferring an output signal to the antenna through a signal path; a coupler for acquiring a first signal coupled to the output signal and a second signal coupled to a reflected signal of the output signal reflected from the antenna; an equalizing module, which changes the magnitude and/or phase of either the first signal or the second signal so as to generate a changed signal; a differential circuit for generating a differential signal between the changed signal and the other one of the first signal and the second signal; and a controller for controlling wireless signal transmission on the basis of the differential signal. Other various embodiments identified through the specification are possible.
