HIGH-FREQUENCY CIRCUIT AND COMMUNICATION DEVICE

Document Type and Number:

WIPO Patent Application WO/2023/058414

Kind Code:

A9

Abstract:

A high-frequency circuit (1A) that can perform uplink MIMO for a first band comprises a power amplifier (30) that can amplify signals in the first band, a first circuit that can adjust the linearity of the output power of power amplifier (30) relative to the input power, a power amplifier (40) that can amplify signals in the first band, and a second circuit that can adjust the linearity of the output power of power amplifier (40) relative to the input power. When uplink MIMO is performed using a first transmission signal that has been outputted from power amplifier (30) and a second transmission signal that has been outputted from power amplifier (40), the first circuit and the second circuit increase the saturated output power of the power amplifiers (30, 40).
