2.2 DRH Functions

This section describes the main functions of the DRH. The Distributed Remote Head (DRH) performs the following functions:



Receives downlink baseband data from the DCU and sends uplink baseband data to the DCU.



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.



The DRH can be powered by the AC/DC power module. In this case, this DRH is called AC DRH.

An DRH consists of a high-speed interface unit, signal processing unit, power amplifier, and dual-duplexer. Figure 2-3 shows the logical structure of the DRH.
