The DMCM receives the service data from the BSC, exchanges and processes it,

and then transfers it to the DDRM

The DDRM performs digital filtering, up conversion, and filter amplification of the

signals and sends the signals to the DDPM

The duplexer in the DDPM filters the signals sent from the DDRM and transmits

the signals through antennas and feeders

The antenna receives the signals transmitted from the MS., then signals are

transmitted to the DDPM

The DDPM receives the signals and transmits the signals to the DDRM after they

are filtered by the duplexer and amplified by the LNA

The DDRM receives the signals and transmits the signals to the DMCM afteramplification and down conversion. The DMCM then transmits the signals to the

S1/2/1 Sector1 and 3 of S1/1/1 share

one DDRM, connect to two

different DDPMs for two

different sectors. The second

sector uses another DDRM

and DDPM


configured as :

DDRM0: no combining

and independent receiver

DDRM2: no combiningand dividing receiver

Power output (dBm)46 -1.0
