Designing with S and Noise Parameters and the Non-Linear
Model
The non-linear model describing the ATF-54143
includes both the die and associated package model.
The package model includes the effect of the pins but
does not include the effect of the additional source
inductance associated with grounding the source leads
through the printed circuit board. The device S and
Noise Parameters do include the effect of 0.020 inch
thickness printed circuit board vias. When comparing
simulation results between the measured S parameters
and the simulated non-linear model, be sure to include
the effect of the printed circuit board to get an accurate
comparison. This is shown schematically in Figure 25.
