Let's say that the IM products need to be only - 20 dB w.r.t
the lowest amplitude value of the various input frequencies. *

Medenhall's paper shows "RF spectrum showing distortion products" that
are 30dB down.

His statement: "If the amplifier is tuned exactly to resonance, the
plate load impedance will be purely resistive and the load line will
be linear." is attached to that linearity which is greater than you
expect.

To Richard Fry,

Richard, it appears that you have ignored my post where I reported
data that proves the output resistance of Class B and C RF amps is non-
dissipative. Have you reviewed or ignored my reference to Chapter 19
in Reflections 3, or the combined sections of that chapter that appear
in my web page at www.w2du.com that uses an example from Terman's
Radio Engineers Handbook? If you haven't yet reviewed it I urge you to
do it, and then if you disagree with my measured data I'd like for you
to explain the reason for your disagreement.
