Achieving both high linearity and high efficiency together in a Radio Frequency (RF) Power Amplifier (PA) system is challenging. Typical designs for highly efficient PAs (i.e., greater than 40% DC power efficiency) involve operating devices in their non-linear range, i.e., at or near compression (saturation). A PA operating in its nonlinear region inherently creates distortion [...]
