Useful for the RF designer, it manipulates the various complex representations of the circuits as multi-ports, namely conversions from one representation to another as well as reading/writing from/to files in industry-standard format.

The (more oftenly used) transformations are singularity-protected; some legacy stuff could be done better today... and it is slowly getting done :-)!

The file parsing/writing in particular has been greatly improved thanks to the input received from the users on this site.

I hope this toolbox will help you when searching for that elusive insight when working at high frequencies !

Have fun !

p.s. any ideas ? bugs ? email me
