The following networks are composed of a shunt C or L (as seen from the analyzer
port), followed by a serial C or L. They are named
Shunt C, Serial C /
Shunt C, Serial L / Shunt L, Serial C / Shunt L, Serial L
.
At the GUI, the "capacitance C<i> in parallel with resistance R<i>" circuit blocks can be
replaced by equivalent "capacitance C<i> in parallel with conductance G<i>" circuit
blocks.
In addition, there is also a
Shunt L, Shunt C
circuit model available, where the
shunt C is defined as a capacitance C in parallel with a conductance G:

Circuit Models for 4-Port Networks
The lumped element 4-port transformation networks for (de-)embedding consist of the
following two basic circuit blocks:
●
A capacitor C connected in parallel with a resistor.
●
An inductor L connected in series with a resistor.
