摘要：
How to accurately control the gate bias voltage of a Doherty RF power amplifier is an important problem that has to be resolved for developing high efficiency RF power amplifiers. This paper proposes a digital bias solution to obtain adjustable accurate bias voltage, and discusses the implementation procedure of high-accuracy bias voltage control software for Doherty RF power amplifiers in detail. The software can not only precisely adjust the bias voltage of a PA to determine the optimal bias point of the PA, but also can be used to build an automatic optimization and debugging system for the power amplifier so as to reduce the fabrication costs of debugging and testing power amplifiers.
