2.2.3 Uplink Path
Uplink Path is similar in structure to Downlink Path.
In case of Downlink Path, RF signal is received from Server Antenna, and through RVS LNA
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 and NF compensation. ALC attenuation range is 20dB, and NF atte
nuation range is 10dB in Digital Step Attenuator.
