Abstract:
The present invention concerns the field of power amplifiers and in particular the enhancement of the performance of the amplifier by a feedback loop acting on the input signal. We present a method for linearizing a power amplifier circuit having as input signal a digital base-band input signal, (x), a power output signal 8z), a power amplifier (PA) and a linearizer module (LM).
