1. Product Overview
Radio Remote Unit (RRU) extends the RF module in the BS to the far-end RF unit through optical fibers to
complete baseband signal and RF signal processing. The RRU and Base Band Unit (BBU) jointly compose
a BS.
Main features of the RRU:
Receiving downlink baseband data sent from the BBU, and sending uplink baseband data to the BBU
to implement communication with the BBU.
Receiving the RF signal from the antenna feeder system, changing the received signal to intermediate
frequency signal through down conversion, performing amplification and analog-to-digital conversion
(A/D conversion) for the signal, completing downlink signal filtering and digital-to-analog conversion
(D/A conversion), and sending the RF signal to the transmit frequency band through up-conversion.
Providing the received signal and transmitted signal multiplexing function of RF channel to enable the
received signal and transmitted signal to share one antenna channel, and providing the filtering function
of received signal and transmitted signal.
