Large-signal or non-linear characterization of transistor devices is essential for determining their performance in such non-linear applications as power amplifiers (PAs), considering the limitations of linear S-parameter characterization techniques in such applications. Load-pull is one of the most frequently used techniques for estimating and optimizing device performance in the non-linear domain.
