Hi,
IIRC, both nanoBTS and SysmoBTS have separate antennas
for Rx andTx and do
not use duplexers. Do we need duplexer for UmTRXv2 if it operates in the low
power mode, without an additional PA/LNA?
Note that both still have internal filters.
Antenna design also plays a role. The nanoBTS uses patch antenna
separated by a lump of metal to minimize direct radiation from TX to
RX.
Cheers,
Sylvain
