2.2 SRXU Equipment

The SRXU is an extended RF interface module that provides two RX channels for RF signals.
The SRXU receives RF signals from the antenna system, down-converts the RF signals to IF
signals, and then transmits them to the RRU after amplification, analog-to-digital conversion,
digital down-conversion, matched filtering, and DAGC. The RRU forwards the signals to the
BBU or the macro NodeB.
