Csmith

CSmith is a Smith chart program with many high-level features and some enhancements compared to previous versions (Look at the help file for details on the extensions).

Csmith can also be integrated into the complete information based system for electrical engineering, ELEKTA (note: the tools included in Elekta are more basic).

With CSmith, you can design matching networks in a similar way to the conventional Smith diagram.

Here are some key features of "Csmith":

￭ element parasitics included ￭ S-parameter blocks and transistors available ￭ easy modifying, rearranging, loading and saving of circuits ￭ export of S-parameters and the complete circuit ￭ performing frequency sweeps and Monte-Carlo analysis ￭ displaying power gain or return loss vs. frequency ￭ stability factor, MAG, available gain, VSWR, etc. ￭ transforming mixed parallel and series RLC combinations

Limitations:

￭ 60 runs trial ￭ S-Parameter import functions are removed ￭ The circuit can contain only up to 8 elements (instead of 14) ￭ Exporting of the automatically created matching circuit of the 1st page is disabled
