摘要: A method and apparatus for efficient power amplification of a wideband signal with correspondingly wide modulation bandwidth includes an envelope detector (220), adaptive split band modulator (270), amplifier (260). The (270) amplifies the low frequency components using class S (760), high B (750). supply (750) is adaptively modified as function amplitude that it amplifies. In this manner, operates at higher efficiency.
