This source is phase synchronized with the PA's exciter, so we have a
steady state system.

We assume small load mismatch (or low injected power towards the PA)
so that the operating point of the PA just changes slightly (to allow
linear approximation).

Thanks Wimpie.

It sometimes takes a bit to get me to realize this type of thing isn't
hard, it's actually simple. My old brain tries to obfuscate things from
itself sometimes.

It Calc 100. Make the difference small.
