Abstract :
A detailed understanding of the factors affecting amplifier linearity can be obtained by performing envelope domain analysis on measured time domain voltage and current waveforms. Analysis of the input and output time varying envelopes provides for a direct observation of amplifier linearization through IF (baseband) source pull.
