It may not be the approach you are familiar with, but I think it is
valid. The transformer just has a lot of core loss, if you use a
ferrite optimized for a much lower frequency. And that loss shows up
as if it were a resistor connected across the ends of the two
windings. If a low loss ferrite (at the operating frequency) is used,
then the impedance across the windings is dominated by inductance, as
one normally expects with a transformer. But the analysis handles the
whole range of cases.


Hi John,

Through these last comments, and those that go before, you have
entirely missed the boat of both the dynamics involved (this is not a
magnetic circuit being described, and there are NO magnetic lines
broken in a typical circuit in a balanced configuration), and the
topology. Specifically to this last, you still do not seem to
comprehend that a coax has three conductors and is a six terminal
device.

I appreciate you taking the time and effort to try to straighten me
out on this, but if there is no magnetic lines broken (whatever that
means) why use a magnetic core? Why wouldn't disks of carbon work
just as well. They are certainly resistive.
