Abstract
A control method and apparatus of a peak amplifier of a Doherty power amplifier are disclosed, wherein, the control apparatus includes a Radio Frequency (RF) switching circuit in a peak amplification branch of the Doherty power amplifier, which is used to control the turn-on and turn-off of the peak amplifier in the peak amplification branch. The method and apparatus avoid a disadvantage that the peak branch in the Doherty power amplifier is turned on ahead of time, thus reducing the power consumption of the peak power amplifier, and enhancing the mass efficiency of the whole power amplifier; and largely reducing the product expense and production expense of the power amplifier compared to the scheme of some manufacturers improving on-time of the peak power amplifier using complex digital circuits.
