Designing with S and Noise
Parameters and the Non-Linear Model
The non-linear model describing
the ATF-55143 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 param-
