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! -- 73, Cecil http://www.qsl.net/w5dxp 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. 73, KA6RUH |
