With respect to your first question, I subscribe to MWJ and, after a
modest amount of looking on the web, find that the MWJ archives seem to
go back only as far as 2002. I was unable to locate a copy of the 1988
paper elsewhere on the web, which seems strange. Perhaps someone out
there has a paper copy and can scan it. I would also imagine that a
paper copy could be located in some university library.
But then, you have probably already been down those same paths.

I do no always agree with the ADS approach and use my own software the ADS
is a very good all-round CAD microwave CAD tool. More on the topic addressed

Perfectly timed article! :-)
I did not have time to go through all the references yet, but I have a few
questions:
1) Is it possible to get
U. L. Rohde, A. M. Pavio and R. A. Pucel, “Accurate Noise Simulation of
Microwave Amplifiers Using CAD,” Microwave Journal, Vol. 31, No. 12, December
1988, pp. 130-141.
somewhere? MWJ is pretty bad when it comes to accessing old issues.
2) How do you come up with accurate noise models/parameters for the transistors?
As far as I can tell, the spice models provided by the manufacturers have
often only a very crude approximation of what the real noise parameters
look like (if any at all) and have to be corrected to match reality.
3) What about the ADS approach do you not like?
4) What is your own software? And would it be possible to get access to it?
Side note: I do not fully understand how spice (or CAE software in general)
performs noise simulation, hence I do not trust it. So the simulations
I do are kind of syntetic that only take certain noise sources into account
which I deemed the ones dominating.
