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 signals to IF signals,
and then transmits them to the RRU3804 after amplification, analog-to-digital conversion,
digital down-conversion, matched filtering, and DAGC. The RRU3804 forwards the signals to
the BBU or the macro NodeB.
2.2.1 Appearance of the SRXU
The SRXU features a modular structure with its ports at the module bottom and on the cabling
cavity.
2.2.2 LEDs on the SRXU
The LEDs, on the LED panel of the SRXU, indicate the running status of the SRXU.
2.2.3 Ports on the SRXU
The ports on the SRXU consist of grounding ports, power supply ports, transmission ports, and
other ports.
2.2.4 Panels of the SRXU
The SRXU has a bottom panel, a cabling cavity panel, and an LED panel.
2.2.5 Engineering Specifications of the SRXU
This describes the engineering specifications of the SRXU.
