2 RRU Introduction
About This Chapter
This chapter describes the RRU.
The RRU performs the following functions:
lExchanges baseband data with a BBU.
lReceives RF signals from the antenna system, converts the received signals into IF signals,
amplifies the IF signals, and performs analog-to-digital conversion. The TX channel filters
downlink signals, performs digital-to-analog conversion, and converts IF signals into
signals applicable to the TX band.
lMultiplexes RX and TX signals on the RF channel, which enables these signals to share
the same antenna path. It also filters RX and TX signals.
2.1 RRU Exterior
