Receives downlink baseband data from the BBU and sends uplink baseband data for the
communication between the BBU and the RRU.
Receives RF signals from the antenna system, down-converts the received signals to IF
signals, amplifies the IF signals, and performs analog-to-digital conversion. The TX
channel filters downlink signals, performs digital-to-analog conversion, and up-converts
RF signals to the TX band.
Multiplexes RX and TX signals, which enables these signals to share the same antenna
path. It also filters the RX and TX signals.
For the RRUs with a built-in Bias Tee (BT), the built-in BT couples RF signals and OOK
signals and transmits them through the TX/RX port A. The built-in BT also supplies power
to the tower mounted amplifier (TMA).
