Using the Best Linear Approximation to Model the Nonlinear Behavior of Supply Modulated Amplifiers
Paper i proceeding, 2011

The nonlinear distortion in supply modulated amplifiers is thoroughly characterized in this paper. An LSNA with a low frequency test set extension is used to simultaneously measure the spectrum around DC and around the RF carrier. The characterization allows for classification of the nonlinear distortion and to determine the relative influence of different paths. The best linear approximation is measured and used to estimate the response of the supply modulated GaN HEMT.
