Maybe we should ask what you are trying to accomplish. Is it more capacity, or
something else?
Because if it's more capacity, you will take such a hit on price and
performance using 2 radios and combiners that you'd be better off with one more
conventional radio. You shouldn't even have to buy a dual core radio to get
approx. double the throughput of an AF11x. Start with the lower throughput and
lower system gain of the AF11X, lose I think someone said ~7 dB for combiners,
pay for 2 radios and combiners, then need external LAG. It's a Rube Goldberg
if you're just trying to get ~1.5 Gbps full duplex capacity, just buy one of
the alternatives that people have suggested like Aviat. Or if money isn't a
big issue and you want to license both polarizations (which I believe you need
to do for the AF11X), then buy a true dual core radio with an OMT and have tons
of capacity for the future. Either way, feel good that you're making efficient
use of spectrum.
If capacity isn't the objective, maybe some more info.
If money is the main issue, yes the AF11X is very affordable, but not if you
have to use 2 of them and some outboard stuff to do what other vendors can do
with one radio.

The problem is keeping one transmitter out of the other. So you have hybrid
combiners and circulators. Those are the only methods I know. You can get both
at 11 GHz with waveguide or SMA connectors.

This is usually done using wave guides rather than at the electrical level due
to the high losses that occur when trying to do it using transmission
lines. It’s a pretty complex piece of waveguide design - not something you
can cobble together. The vendors with full product lines in the microwave
backhaul market have these solutions already designed and available.
