Abstract
As next generation wireless communication systems move to higher data rates, the bandwidth (BW) and peak to average power ratio (PAPR) of the signal increase. Envelope tracking power amplifier systems provide a means to efficiently amplify these complex waveforms. Envelope power modulators paired with various amplifiers are presented with high efficiency and linearity‥
