Abstract
An apparatus for power amplifier control is provided, applied to a multi-stage power amplifier. The apparatus controls an input voltage of an amplification triode in the first amplification stage, by using a detected current change at a base of an amplification triode in the last amplification stage, achieving control of output power and a maximum output current of the multi-stage power amplifier, greatly reducing an influence of current detection on maximum output power and maximum output efficiency of the power amplifier.
