In order to support CAD design and optimization of Power Amplifiers (PAs), using input second harmonic tuning, it is important that non-linear behavioral device models can accurately describe the high levels of input harmonic injection coupled with output fundamental and harmonic injection. This paper presents a tailored mixing model formulation that was used to extract input and output harmonic model...
A solution allowing for the rapid, cost effective and accurate extraction of nonlinear Direct Waveform Look-Up table (DWLU) based behavioral models is presented in this paper. The behavioral model extracted is a reformulation of the PHD model, now defined about a non 50-Ohm reference impedance, enabling it to accurately predict load-pull contours. The technique exploits a simple active and passive...
