The RRU performs the following functions:

Receives downlink baseband data from the BBU and sends uplink baseband data to the
BBU.
Receives RF signals from the antenna system, down-converts the signals to intermediate
frequency (IF) signals, amplifies the IF signals, and performs analog-to-digital
conversion. The transmit (TX) channel filters downlink signals, performs digital-toanalog conversion, and up-converts RF signals to the TX band.
Multiplexes receive (RX) and TX signals on the RF channel, which enables these signals
to share the same antenna path. It also filters the RX and TX signals.
Provides 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).
The RRU can be powered by the AC/DC power module. In this case, this RRU is called
AC RRU. For details about the AC/DC power module, see the AC/DC Power Module
