From the IEEE Dictionary: "directional coupler - a two port circulator"
Heh, heh, just kidding. :-)

Heh, heh... Actually the closest thing to a "two port circulator" is an
"ideal
transformer" it has the same scattering matrix as a two port circulator.
BTW... here's an interesting rhetorical question that is often posed
in texts on the scattering matrix.
How many different kinds of three port circulators are there?
