Radio-frequency circuit and communication device

A radio-frequency circuit, comprising:

• a first power amplifier configured to amplify a first transmission signal and to output a first amplified transmission signal;
• and
• a second power amplifier configured to amplify a second transmission signal having a different frequency than the first transmission signal, and to output a second amplified transmission signal, wherein:
• when (1) both the first power amplifier and the second power amplifier output the first and second amplified transmission signals, respectively, and (2) a value indicating an output power of the first power amplifier or the second power amplifier is greater than a first threshold power, the first power amplifier or the second power amplifier is configured to switch from an envelope tracking amplification mode to an average power tracking amplification mode.
