A laboratory bench setup is simpler than a calculator and a couple
of sheets of paper? Egads Richard, s-parameter analysis was invented
in order to make things "vastly simpler" - and it does!

S-parameters are supposed to work best on small-signal analysis, where
everything is fairly linear. In this case, the MRF 136 is a power fet and
Motorola
says you can use s-parameters as a first approximation. In the data sheet, they
provide a list
of common source scattering parameters from 2.0 Mhz up to 800 Mhz. I suppose
that's useful to someone familiar with s-parameter techniques.
