Figure 2-3 Function structure of the RRU

NOTE

For details about the extension ports, see 2.4 RRU Ports.

The RRU performs the following functions:

l Receives downlink baseband data from the BBU and sends uplink baseband data to the

BBU.

l 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-to-analog conversion, and up-converts RF signals to the TX band.

l 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.

l 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).

l 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 User Guide or OPM15M User Guide.

2.3 RRU Technical Specifications

This section describes technical specifications of an RRU, including supported modes, frequency bands, RF specifications, engineering specifications, and antenna capabilities.

For details about technical specifications of an RRU, see section "Technical Specifications of RRUs" in the 3900 Series Base Station Technical Description.
