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.

Some Information (a) The nominal passband gain is 37dB; (b) The nominal bandwidth of band 2600M (DRH3926A)is 73.07MHz; (c) The rated mean output power is 2*20W; (d) The input and output impedance are 50Ω; (e) The following notice:”The Manufacture’s rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present, the rating would have to be reduced by 3.5dB, especially where the output signal is re-radiated and can cause interference to adjacent band users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device.”
