~~~~~~~~~~~~~~~~~~~~~~~~~~~
HP has posted a very nice RF Design Tool software for Win95/NT4 on their
web page for free download. It includes application notes, design tools
for active and passive circuits, and system tools. Included is 10 models
of transmission lines, including circular coaxial, square coaxial,
microstrip, slab line, coplanar-waveguide, etc. Also included is a nice
reflection calculator.
It is called AppCAD and the downloadable self-install exe file is 5.9 MB
in size. URL is http://www.hp.woodshot.com/
