•
A capacitor C connected in parallel with a resistor.
•
An inductor L connected in series with a resistor.
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 , the shunt Rs are set to 10 M . 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 Touchstone file
(*.s4p). No additional parameters are required.
The following networks are composed of a shunt C or L and two serial elements, described by means of
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 C / Serial Cs, Shunt L / Serial Ls, 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 C, Serial Cs / Shunt C, Serial Ls / Shunt L, Serial Cs /
Shunt L, Serial Ls.
