Me too, but zero source impedance does not match the load as required
for maximum power transfer.

It seems to me that much too much is made of 'maximum power transfer'
in
the RF world. In the world of 50 and 60 Hz, where significantly more
energy is moved, 'maximum power transfer' is never mentioned.
Efficiency
is much more of interest.

For the most part, 'maximum power transfer' is just an interesting
ideosyncracy of linear circuit theory.
