The RF power amplifier (PA) is a nonlinear system with an intrinsic and dynamic feedback mechanism. The application of an adequate linearizer (which is also a nonlinear dynamic system) inserted at the input of the signal path (i.e., predistortion) is very important to maintain a linear transmission
