Title:
ELECTRONIC DEVICE FOR TRANSMITTING RADIO FREQUENCY SIGNAL AND OPERATION METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/013939
Kind Code:
A1
Abstract:
An electronic device comprises at least one communication processor, an RFIC, at least one power amplifier, and at least one converter. The at least one communication processor may be set to: on the basis of an APT mode, set a first voltage to be a drive voltage which is applied to a first power amplifier, among the at least one power amplifier, for amplifying a first RF signal provided from the RFIC; control at least some of the at least one converter so that the first voltage which has been set on the basis of the APT mode is provided to the first power amplifier during a transmission period of the first RF signal; and on the basis of the occurrence of an event associated with audible noise, control at least some of the at least one converter so that the first voltage is provided to the first power amplifier during at least some periods among the remaining periods in which an RF signal is not transmitted.
