Power amplifier linearization with extinction based feedforward methods and systems

Linearizer the linearity of power amplifiers can be improved by making an amplitude non-linearity of components (such. As IM3, IM5, IM7, IM9, etc.) to extinguish or diminish, which are generated by the power amplifier. The linearizer can win samples of signals output by the power amplifier, and process the samples to generate a cancellation signal, which is applied on or in an output of the power amplifier. The cancellation signal is generated such that it cancels a part of the non-linearity components generated by the power amplifier when applied to the output of the power amplifier at least or reduced. A control unit can improve the correction of non-linearity components by performing one or more tuning algorithms and adjusts settings of the linearizer based on the results of the algorithm or algorithms.
