LibreCellular and LimeRFE

I’m installing the LibreCellular setup with a LimeSDR USB & LimeRFE cellular

Since the cellular output is only J3 on LimeRFE there is no need for that Sysmocom RF Duplexer right ?
Also, do i need a mandatory J12 communication on LimeRFE with LimeSDR to make it work and get the correct switching between Rx/Tx ?

Thank you, great pieces of Hw ! :ok_hand:

Yes, it integrates duplexers for the cellular bands supported.

What band are you planning to use? Most LTE bands are FDD and so transmit and receive at the same time, with no switching. Not sure if we’ve considered TDD use with LimeRFE.
