Figure 2-3 Function structure of the RU

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

The RU 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-to-analog 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 RU can be powered by the AC/DC power module. In this case, this RU is called AC RU. For details about the AC/DC power module, see the AC/DC Power Module User Guide or OPM15M User Guide.

2.3 RU Technical Specifications

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

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