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). It 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, but there are a number of far more powerful new features :

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
