Fig. 7.9 Equivalent T model for the 3-terminal transformer

Fig. 7.10 Low-frequency equivalent T model for the 3-terminal transformer parameter extraction

Fig. 7.11 High-frequency equivalent circuit for the 3-terminal transformer parameter extraction

The model of Fig. 7.8 , with the parameters of Table 7.3 , was simulated and
compared with the measurement data. The parameters S 21 and S 11 are shown in
Figs. 7.12 and 7.13 . The measured and extracted characteristics are in good agree-
ment if we consider that the values of the components in the model are constant with
