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‥
