Abstract:
An envelope tracking power amplifier system comprising an RF input path and an envelope path for providing a modulated power amplifier supply, further comprising a plurality of envelope detectors for detecting the envelope of a plurality of frequency bands of an input signal and each generating an output signal, and a combiner for combining the output of the envelope detectors.
