Figure 2: RX-1839 Functional Block Diagram
In the downlink, the BTS signals are received by donor antenna of the repeater. After the duplexer, the
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 at 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.
