Behavioral model analysis using simultaneous active fundamental load-pull and harmonic source-pull measurements at X-band

Summary form only given, as follows. To support recent interest in improving PA performance via input waveform engineering it is important that non-linear behavioral device models can accurately describe the high levels of input harmonic injection necessary. This paper presents a model formulation used to extract input harmonic model coefficients from a set of 9 GHz active source/load-pulls measurements. The resulting 4th order model was sufficient to capture the response of the scattered [b] waves to a maximum confidence of 99.46%.
