Can we use rat-race coupler for IC's with balanced output?
https://www.microwaves101.com/encyclopedias/rat-race-couplers
For example, connect port 2 and 4 to balanced output of IC, and port 1 to antenna?
(Numeration of ports as on image on microwaves101 page)
At 2.4GHz it would be a big coupler, but we can put ic's and other stuff inside empty space in it's radius... Also it can be pretty at higher frequencies, say 5 and 10GHz if such IC's exist.

A rat race coupler would do the job, but it is somewhat overkill. Wire-wound baluns are more common (much smaller).
