2 EQUIPMENT DESCRIPTION
2.1 SYSTEM DIAGRAM
In the downlink, the BTS signals are received by donor antenna of the repeater. After the duplexer, the
Figure 2: 2 Bands System Diagram for Example
signals are sent to the LNA module for pre-amplification and digital RF integrated module for digital
filtering and frequency conversion. Then the DL signals will be sent to downlink PA to amplify power and
filter via duplexer. After amplification, the signals are transmitted via the MT port to the service antenna.
In the uplink, the mobile signals are received by the service antenna. After the MT port integrated
duplexer, the signals are sent to the LNA, integrated module for digital filtering, then to PA for power
amplification and to duplexer. After that, the uplink signals are sent to the donor antenna for transmission
back to the BTS.
