Updated July 5,
In all types of electrical engineering,
the term "CAD" is rapidly being replaced with "EDA",
which stands for "electronic design automation". We're
going to stick with "CAD" since it's faster to say, and
everyone knows what it means, including the politically incorrect
double-entendre in the Rhett Butler sense (which is no-doubt why
the feminized software industry has switched to "EDA"!)
But let's stop digressing... again...
Update July 2009: we've
changed the rules on this page and many others. In the interests
of providing information to our readers, we will continue to list
software suppliers, but we will no longer maintain links to their
web sites for free. Instead, you will be linked to
this page, which will soon be one of our most popular in terms
of page views. If you are a supplier, we'll rent you a link on this
page or any other page, but it won't be for free. Contact
Being primarily hardware guys
(by "guys" we mean all possible sexes) at Microwaves101,
we try not to refer to software as tools. Software is software,
you use it while sitting your increasingly soft butt in a chair.
Tools are those things that real men (and men-like women)
use in the garage or around the house, while skinning knuckles and
getting grease, paint and dirt on their pants. Hey, that was a seriously
incorrect statement, oops, there goes another potential sponsor...

Here's a list of software suppliers.
Guess how many of the links are "live?" One of these days
we'll sort this list into a table that shows linear, EM, layout,
transient, etc. capabilities. Maybe someone else would like to take
a crack at this for a free
Design System (ADS)
Software for coplanar-waveguide
Many companies out there offer
specialized software that works in conjunction with linear optimizers.
There is at least one company that specializes in a simulation tool
for CPW, called Coplan.
There are a large number of vendors
selling filter design software these days, check the ads in any
microwave trade journal. You can
download a fair amount of filter design software on the web for
free, nerds have been writing their own filter code for as long
as there have been computers. Heck, even Microwaves101 offers a
free download for lumped filter
Coming soon! Or not!
