Hi,
It still exposes independent TX and RX lines allowing for external
amplification / filtering if required.
Also in a duplexer you have a direct electrical connection rather than
TX->RX radiation which means you need much more attenuation (often
requiring the duplexer + subsequent band pass filters).
Cheers,
Sylvain
nanoBTS has
both side. You can clearly see them here :

sysmoBTS I know has RX filters, I don't remember about TX.
Hum, I don't see how is that different from a duplexer if they have
both Rx and Tx filters. Do you know any particular reason for this
design?
