2.2.3 Uplink Path
Uplink Path is similar in structure to Downlink Path.
In case of Uplink Path, RF signal is received from Server Antenna, and through RVS division,
then the signal is transferred to IF division, where desirable Band is selected by Digital Filter.
Selected Band is transferred to RF division again, and through RVS PAM, after that the signal is
transmitted to BTS through Donor Antenna.
Two attenuators use for ALC compensation. ALC attenuation range is 40dB.
