Electronic device and harmonic control method of electronic device

Abstract

An electronic device according to an embodiment of the present disclosure may comprise: a processor; a memory electrically connected to the processor; a power management integrated circuit (PMIC) electrically connected to the processor; a radio frequency integrated circuit (RFIC) electrically connected to the processor; a power supply module including a power supply electrically connected to the PMIC and the processor; a front-end module including circuitry\electrically connected to the PMIC, the RFIC, and the power supply module, and is configured to modulate and amplify an RF signal received from the RFIC; a variable notch filter electrically connected to the power supply module and the front-end module, and connected to a transmission signal amplifier of the front-end module and configured to remove a harmonic frequency; and an antenna electrically connected to the front-end module, wherein the processor is configured to: control the PMIC and the power supply module to supply power to the front-end module; control a wireless communication operation to be performed using multiple frequency bands; and based on performing the wireless communication operation using the multiple frequency bands, control impedance of the variable notch filter to adjust a frequency removal band of the variable notch filter based on a parameter pre-stored in the memory.
