Sounds like good articles!

W/o having read them, I'll confess that I am at a loss to know the back
ground.  What is the debate?

Also, generally when determining a conjugate match, S-Parameters are used at
the small signal level.  How are they measuring large signal S-parameters or
are they using one of the other types of network parameters (Z, H, etc) to
do it?

Also such techniques are generally applied to linear systems.  But since the
"match" of a class B or C amplifier is not a constant impedance, how are
they going about determining the conjugate?

I'm sure that's what the debate is about or something similar.  Give us the
Cliff notes, Phil!

Thanks,

Jon
