Doherty Goes Digital: Digitally Enhanced Doherty Power Amplifiers

IEEE Microwave Magazine, 2016
Efficiency enhancement techniques for high-power amplification systems are now mature technologies, with Doherty power amplifiers (PAs) being widely used in field-deployed wireless base stations. A typical Doherty PA consists of two parallel amplifiers (a carrier amplifier, biased in class-AB, and a peaking amplifier, biased in class-C), an input ...
