According to various embodiments, an electronic device may include: a communication processor, a radio frequency (RF) integrated circuit (RFIC) configured to receive a signal output from the communication processor and to modulate the signal into an RF signal, a power management circuit, a first power amplifier configured to amplify an RF signal output from the RFIC based on power supplied from the power management circuit, a second power amplifier configured to amplify the RF signal output from the RFIC based on the power supplied from the power management circuit, at least one capacitor connected in parallel to a power supply terminal of the first power amplifier, and at least one switch connected between the power supply terminal and the at least one capacitor, wherein the communication processor is configured to: identify a power amplification mode based a frequency band of the RF signal, and control the at least one switch by outputting a control signal corresponding to the identified power amplification mode.

Electronic device including power amplifier and front-end module including power amplifier

An electronic device includes a first antenna that transmits/receives a signal in a first frequency band, a second antenna that transmits/receives a signal in a second frequency band, a first wireless communication circuit connected with the first antenna, a second wireless communication circuit connected with the second antenna, at least one processor connected with the first and second wireless communication circuits, and a memory. The memory stores instructions that cause the processor to output a first signal with a first power to control the first wireless communication circuit to output the first signal through the first antenna, and output the first signal with a power, which is obtained by backing off from the first power as much as a first backoff value, to control the second wireless communication circuit to output a second signal through the second antenna while controlling the first wireless communication circuit to output the first signal.

Electronic device comprising antenna and power backoff control method for the electronic device

The disclosure relates generally to an electronic device for providing a character input function and a method for controlling thereof. The electronic device includes: a display; and a processor configured to output a character input screen through the display, to change a configuration of the character input screen by magnifying at least part of a first area of the character input screen and reducing at least part of a second area of the character input screen based on a first input on the character input screen, and to select a character based on a second input on the changed character input screen. Various example embodiments are possible.
