Good to see that everyone agrees that a generator with a resistor in series is
an unsuitable model for an RF transmitter.The easy part of the work is done!

Now the more difficult part. As, by the Thevenin theorem, any complex circuit
comprising resistors, voltage generators and current generators is equivalent to
a generator with a resistor in series, evidently the transmitter model must
comprise elements other than just resistors, voltage generators and current
generators.

Can one suggest how such a model looks like? (even a plain one, that does not
take into account second- or superior-order effects).
