The wikipedia definition of "return loss" is rather absurd. If you have a
*perfect* match and *no* power is reflected, the "return loss" is
infinite. Of course it *is* wikipedia.
I'm not about to try to change the EE community lexicon, but it seems to
me reflected/incident makes a great deal more sense numerically. It also
leads to what I'd expect. "Loss" as a negative quantity when expressed in
dB.
Have Fun!

What¡¯s the i*nsertion loss* of a 6 dB attenuator? I would have thought it
was 6 dB and not -6 dB.
The same with return loss.
