i´m looking for a possibility to use S-Parameter (.s2p-files) in LTspice. Is there any possibility to implement the .s2p-file to LTspice or convert the .s2p-file in a file which LTspice can use? If it´s possible the program should be freeware.
I have written a program "s2spice.exe" to convert S-parameter to subcircuits. There may be other programs on the Web too. My program and examples are in LTspice Yahoo group. https://groups.yahoo.com/neo/groups/LTspice/info
It's ncessary to join this group, when you want download the files. The converted circuit is 100% perfect in a .AC-analysis, but a .TRAN simulation will be mostly disappointing.
Below is the link to the theory and the procedure about using the S-parameters in (P)SPICE.
I have now attached an example including my program to convert the S-parameter file to a ".lib" file with the subcircuit for the simulation in (LT)SPICE. Please read the comments in the schematic.By the way one can plot S,Y,Z-parameter with LTspice using the .NET command line. See the help pages in LTspice.
This is very helpful, thanks!!
