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

You mean
bandpass filters? Are they only on Rx side or both Tx and Rx?
Yes, bandpass filters. (SAW or Ceramic, possibly both)
nanoBTS has both side. You can clearly see them here :

sysmoBTS I know has RX filters, I don't remember about TX.
