摘要：A multistage amplifier and design method are disclosed. The multistageamplifier has a plurality of amplifier stages, each stage having an amplifier designed and
biased to operate at or near the amplifier's power added efficiency (PAE) peak. The PAEpeak of each of the amplifier is at or near the amplifiers linear-compression transitionregion, providing a multistage power amplifier that is power efficient and has desirableamplitude to amplitude and amplitude to phase power transfer characteristics. Theamplifier is designed by matching the output impedance of a final stage with a load.Amplifier stages are iteratively designed from the last stage to the first. At each stage, anamplifier and drive circuit are designed. The drive circuit and amplifier are designed toprovide each stage with output impedance matched to the input impedance of thefollowing stage and to operate at or near the PAE peak of the amplifier.
