Perhaps that rumor is just an urban legend, however, and non-linear
outputs are welcome.


The subject is modeling a class-C source, Gene,
not filtering a class-C source. We all know how
to filter a class-C source. Do you have a model
for a class-C source?

Well, we used to have one waaay back in Non-linear Transistor Design.
Done with harmonics and relatively simple math as I remember. Gave
remarkably accurate answers only using the fundamental plus 2 or 3 of
them. The course was mostly about tank circuits, doublers, triplers,
PLLs, etc. though, since the non-linear stuff was so easy once learned.

Of course it wasn't really a model of a class-C source, since it
actually did anything you could think of. So I guess it wouldn't qualify.

Sorry I mentioned the concept.
