• 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.
