Title:
HIGH FREQUENCY CIRCUIT, COMMUNICATION DEVICE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2022/259811
Kind Code:
A1
Abstract:
A high frequency circuit (1) comprises: a power amplifier (11) connected to an antenna connection terminal (101); a power amplifier (12) connected to an antenna connection terminal (102); a low-noise amplifier (21) connected to the antenna connection terminal (101); and a low-noise amplifier (22) connected to the antenna connection terminal (102). The power amplifier (11), when a first SRS of a band A is output via an antenna (2a), amplifies the first SRS in accordance with a first amount of degradation of the S/N ratio of the band A due to distortion of a transmission signal of a band B that flows in via the antenna (2a). The power amplifier (12), when a second SRS of the band A is output via an antenna (2b), amplifies the second SRS in accordance with a second amount of degradation of the S/N ratio of the band A due to distortion of the transmission signal of the band B that flows in via the antenna (2b).
