PUFF microwave CAD software on Linux

PUFF is the name of a computer aided design program for microwave circuits, developed at the California Institute of Technology. It allows one to easily edit a circuit and calculate and plot the circuit's scattering parameters. It was originally created under MS-DOS in the 1980s and 1990s, and distributed for a modest fee together with a manual and sourcecode. Since late 2000, this web page contained information on how to compile it under Linux.

In early 2010, the original program was made available under the GPLv3 license, and therefore a complete Linux package is now available for free here, including the original manual: here it is.
