Paul,
No, hybrid ring is totally different. The cavity / isolator example I
referenced is similar to a normal duplexer with the exception of using a
five way star "T" and then critical length jumpers from the "T" to each
cavity. There is another form of cavity / isolator combiner that uses an
isolator and two cavities per channel in a daisy chain format that can
be used for many channels at a time. Look at Telewave (among others) for
an overview of T-pass style combiners.
