I have obtained several small rf transistors, including a NTE311 (similar to
a 2n3866) and a NTE278 (similar to a 2n5109). I have spent a few hours
reviewing several books I have (primarily RF Circuit Design by Chris Bowick)
and have at least indentified the fact that I am much more in the dark than
I first thought
I see now that I can dc bias a transistor for class A operation, and then
design a conjugate match for the source impedance and the load impedance.
Unfortunately, most of the examples assume you have Y or S parameters on
your data sheet, which I do not...not for any frequency, much less 110mhz.
So I either need to guess, measure or locate these parameters for the NTE278
and the NTE311. Suggestions?
Thanks,
Hank
