Title:
POWER AMPLIFICATION CIRCUIT AND HIGH-FREQUENCY CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/127397
Kind Code:
A1
Abstract:
A power amplification circuit (10) is equipped with a power amplification instrument (11) that, if a first signal (S1) of a first channel and a second signal (S2) of a second channel are simultaneously transmitted, amplifies the first signal (S1) and the second signal (S2). If the frequency gap between the first channel and the second channel is smaller than a first threshold width (WTH1), an ET mode is applied to the power amplification instrument (11). If the frequency gap is greater than or equal to the first threshold width (WTH1), an APT mode is applied to the power amplification instrument (11).
