“…In this section, we show load-pull power contours of an amplifier as a means of checking the logical correctness of ( 17) and the SFG theory that lead to it. Note, however, that the numerical accuracy offered by load-independent X-parameters that we use in the following examples for simplicity is known to be limited to a small region on a Smith chart [21] (around the origin in our case). The accuracy could be improved, for example, by shifting the region of good accuracy to a region of interest (e.g.…”

“…The yellow ones relate harmonics with subscripts with the same sign in the input and output spectra. They are usually called Y S in the bibliography [5], [6] through the analogy with the X-parameter subsets. The blue ones relate harmonics with subscripts with different signs and are usually called Y T .…”

“…However, for modelling transistors, the Admittance V-I domain would be more physical. In recent years, several alternative admittance behavioural formulations have been proposed [5][6][7][8][9]. They basically follow the same assumptions behind X-parameters or the Cardiff model and require phase normalization, but their formulations consist of NL algebraic maps of (total) voltages and currents phasors, for the different spectral components, at the transistor ports (V-I domain).…”
