2 EQUIPMENT DESCRIPTION
2.1 SYSTEM DIAGRAM
Figure 3: PS DAS Functional Block Diagram
In the downlink path, the BTS signals are received by the donor antenna of the Master Unit. After the duplexer,
the signals are sent to the LNA module for pre-amplification and to the digital RF integrated module for digital
filtering and frequency conversion. Then the DL signals will be sent to the Remote Unit to amplify power by
optical fiber, and filter via the duplexer. After amplification, the signals are transmitted at the MT port to the
service antenna.
In the uplink path, the mobile signals are received by the service antenna. After the MT port duplexer, the
signals are sent to the LNA, integrated module for digital filtering, then the UL signals will be sent to the Master
Unit for power amplification and to the duplexer. After that, the uplink signals are sent to the donor antenna for
transmission back to the BTS.
The devices can detect output power, refer to expect output power which is set by user, the device can reduce
or increase internal ATT automatically and remain the expected output power. This is the AGC principle.

2.3 EQUIPMENT CONSTITUTION
The typical PS DAS unit consists of the following components:
Power Amplifier (PA): It provides power amplification for both the UL and DL branches.
Main Control Unit (MCU): The MCU is used to monitor and control the operation of the repeater. It also
provides the communication interface for remote control and status indication. LED indicators provide the
operation status of the MCU.
Duplexer: The DPX is located near the MT and DT terminals and permits the uplink and downlink signals to
share a common antenna.
Digital Integrated Module and Power Amplifier: Consists of the Power Conversion module, RF module,
digital process module and monitoring modules. The Power Conversion module converts +28V DC voltage into
+9VJK and +9VRF. +9VJK, +9VRF are supplied to the monitoring unit, and the RF unit in the integrated module
separately. The RF module amplifies and converts the RF signal to IF signal. The Digital process module
converts the IF signal into baseband signal via AD conversion and extraction, and filtering. After that, the IF
signal will be amplified and converted to an RF signal by the RF module for RF filtering and amplification. The
Monitoring module monitors and controls the system parameters and is the interface for both remote
monitoring and local commissioning.
Power Supply Unit (PSU): The PSU converts the input voltage into a stable DC supply to provide power for
the internal functional modules.
Optical module: Completes optical signal and RF signal conversion.
