I really do not like to see Rhea dissed this way. Yes, nonlinear sim may
buy another dB or two,
but in the end one has to stay at least somewhat linear, lest one builds
an 1/f upconverter.
(and Harbec does nonlinear.)
Others don't even have their linear basics complete; everybody talks
loop gain but
nobody shows how you get from your network analyzer to the correct
answer of a
circuit whose output is terminated with its own input and whose input is
with its own output. It took Rhea to present that on page 3 or so.
And I see a lot of examples compared to actual measurements, and the
Genesys design kits simply work. In fact, Rhea's Genesys is the one
saved me most of the time, and that includes LTspice, which says a lot.
He more or less forced Agilent to buy a competitor from the market, while
they had their own ADS. (which tries to be everybody's darling, nothing it
can't do, but it is too complicated if you do not use it every day.)

Silly me, I've bought it. But his book on digital radio is much better.
