Title:
ELECTRONIC DEVICE AND HARMONIC CONTROL METHOD OF ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/216106
Kind Code:
A1
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 electrically connected to the PMIC and the processor; a front-end module which is electrically connected to the PMIC, the RFIC, and the power supply module, and modulates and amplifies an RF signal received from the RFIC; a variable notch filter which is electrically connected to the power supply module and the front-end module, and is connected to a transmission signal amplifier of the front-end module 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 by using multiple frequency bands; and when performing the wireless communication operation by using the multiple frequency bands, control impedance of the variable notch filter so as to adjust a frequency removal band of the variable notch filter on the basis of a parameter pre-stored in the memory.
