Issue 03 (2014-01-20) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. RRU3832&RRU3632 Hardware Description 2 RRU Introduction 2.1 RRU Exterior This section describes the exterior and dimensions of an RRU. Figure 2-1 shows an RRU. Figure 2-1 RRU exterior Figure 2-2 shows RRU dimensions. Figure 2-2 RRU dimensions 2.2 RRU Functions This section describes the main functions of the RRU. The Remote Radio Unit (RRU) consists of the high-speed interface unit, signal processing unit, power amplifier, duplexer, extension ports, and power module. Figure 2-3 shows the function structure of the RRU. Issue 03 (2014-01-20) Huawei Proprietary and Confidential Copyright © Huawei Technologies Co., Ltd. RRU3832&RRU3632 Hardware Description 2 RRU Introduction 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: 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 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.

A fixed-length RF jumper used by an RRU is 2 m (6.56 ft), 3 m (9.84 ft), 4 m (13.12 ft), 6 m (19.68 ft), or 10 m (32.81 ft). A variable-length RF jumper used by an RRU has a maximum length of 10 m (32.81 ft). NOTE l When the distance between an RRU and an antenna is less than 10 m (32.81 ft), one end of the RF jumper is connected to the ANT-TX/RXA or ANT-TX/RXB port at the bottom of the RRU, and the other end is connected to the antenna. l When the distance between an RRU and an antenna is greater than 10 m (32.81 ft), one end of the RF jumper is connected to a feeder, and the other end is connected to the antenna. l If the customer prepares the RF jumper, the length of the RF jumper should be as short as possible and not exceed 2 m (6.56 ft.). Exterior An RF jumper has a DIN male connector at one end and a customized connector at the other end. Figure 3-9 shows an RF jumper with a DIN male connector at each end.

When the RRU is connected to the RET antenna, an AISG multi-wire cable transmits RS485 signals. The length of the AISG multi-wire cable is 5 m (16.40 ft). NOTE An RCU is a driving motor used for the phase shifter in the RET antenna. It receives control commands from a base station and runs the commands to drive the stepper motor. Using a gear, the stepper motor drives the adjustable phase shifter in the antenna and changes the downtilt angle. Exterior An AISG multi-wire cable has a waterproofed DB9 male connector at one end and a standard AISG female connector at the other end, as shown in Figure 3-10.
