[0002] As the core component of the RF front end, the power amplifier should conform to the development trend of system intelligence. However, the conventional power amplifier design is aimed at a specific use condition and it is difficult to meet the requirements of intelligence, integration and efficient operation in complex environments. Therefore, it is necessary to study reconfigurable power amplifiers, which will greatly simplify the system complexity and improve system performance.

[0003] However, the existing reconfigurable power amplifier cannot adjust the amplitude and phase of the control signal at the same time, and needs to know the state information of the input RF signal in advance, and then make adjustments manually according to the input RF signal state information.
