Description
l
Amplifies downlink RF signal input via the RTR and then sends the
signal to the DFL
l
Provides digital pre-distortion feedback signals for the RTR
l
Provides a PA output enable/disable interface
l
Performs filtering and low noise amplification of the reverse CDMA
signal from the antenna
l
Filters the forward RF signal to be sent
l
Reports LNA alarms to the RTR
l
In the case of main/diversity combined cabinets, the main receive LNA
output end of the DFL has the power splitter function and reserves
an external port (Rx out)
Converts -48V DC input power supply to DC power supply required by
the PA, RTR, or DFL
BBU
enters the RTR, and then for intermediate frequency
CDMA
signals from the antenna are converted to baseband digital signal
