The transformation networks comprise various combinations of 3 basic circuit blocks,
where two blocks represent serial elements, the third a shunt element. In the default
setting the resistors are not effective, since the serial Rs are set to 0 Ω, the shunt Rs
are set to 10 MΩ. Moreover, the serial elements can be replaced by imported 2-port S-
parameters, or the entire transformation network can be described by imported 4-port
S-parameters.
The first network is defined by its S-parameters stored in an imported four-port Touch-
stone file (*.s4p). No additional parameters are required.
The following networks are composed of a shunt C or L and two serial elements,
described by imported 2-port S-parameters. They are named
Serial 2-port, Shunt C / Serial 2-port, Shunt L /
Shunt L, Serial 2-port / Shunt C, Serial 2-port.
The following networks are composed of two serial Cs or Ls (as seen from the analyzer
test port), followed by a shunt C or L. They are named Serial Cs, Shunt L /
Serial Ls, Shunt C / Serial Cs, Shunt C / Serial Ls, Shunt L.
The following networks are composed of a shunt C or L (as seen from the analyzer test
port), followed by two serial Cs or Ls. They are named Shunt L, Serial Cs /
Shunt C, Serial Ls / Shunt C, Serial Cs / Shunt L, Serial Ls.
