Title:
ELECTRONIC DEVICE AND METHOD FOR PROCESSING HARMONIC SIGNAL
Document Type and Number:
WIPO Patent Application WO/2020/153816
Kind Code:
A1
Abstract:
An electronic device in a wireless communication system according to various embodiments may comprise: a processor; a power amplifier (PA) for a first frequency band; a low-noise amplifier (LNA) for a second frequency band which at least partially overlaps a frequency band that is twice as wide as the first frequency band; and an impedance tuner which is in a first impedance state or a second impedance state according to control of the processor, wherein the power amplifier and the impedance tuner are connected electrically together, and the amount of harmonic output from the power amplifier in the first impedance state is greater than the amount of harmonic output from the power amplifier in the second impedance state, wherein the processor controls the impedance tuner to the second impedance state when communicating in both the first frequency band and the second frequency band, and controls the impedance tuner to the first impedance state when communicating only in the first frequency band.
