An electronic device may include at least one communication processor, an RFIC, at least one power amplifier, and at least one converter, the at least one communication processor is configured to identify at least one first driving voltage corresponding to at least one first transmission power of at least one first RF signal, control a first converter corresponding to a first power amplifier among the at least one converter, so that the at least one first driving voltage is applied to the first power amplifier corresponding to the at least one first RF signal among the at least one power amplifier, identify at least one second driving voltage corresponding to the at least one first transmission power of the at least one first RF signal, control the first converter so that the at least one second driving voltage is applied to the first power amplifier.

Electronic device for transmitting RF signal and operation method thereof

A method of controlling power supply for amplifying a radio frequency (RF) signal includes: determining whether a power supply mode for supplying power from a power modulator of a communication apparatus to an amplifier for amplifying the RF signal is an envelope tracking (ET) mode for supplying power based on ET of the RF signal; when the power supply mode is the ET mode, determining whether a downlink block error rate in the ET mode and a downlink modulation method in the ET mode satisfy a first condition; when the first condition is satisfied, determining whether a full resource block (RB) in an uplink band is allocated to uplink data transmission; and when the full RB in the uplink band is allocated to uplink data transmission, switching the power supply mode to an average power tracking (APT) mode for supplying power based on average power of the RF signal.
