thanks for a great tip! Downloaded the 2MBsetup-file. Runs great on my
XP machine and I am confident it will be very handy! Never heard of
this one before! Thumbs up!

Depending on what you want to do, you might try RFSIMM99 which is a fairly
powerful S parameter simulator program.

It is free and if you do a search for that name you ought to get a lot of
sites to download it from.

=============

When I set the passive components to use real world models, I can enter
the self resonant frequencies and so on from the catalog for the particular
component I want to use.

Then, running Random Simulation mode, I can find if my design has critical
components. I like that !!!

The ability to include real world parasitics is a nice part of the
program, and I use it to keep my designs as tolerant of the actual
components as possible.
