PRODUCT DETAILS

DTRU module is B8018’s main module, it mainly completes the control and processing of wireless channel of two-channel carrier in GSM system, the transmission and reception of wireless channel data, the modulation and demodulation of baseband signal on wireless carrier, and the transmission and reception of wireless carrier function and so on.

DTRU consists of four functional single boards:

• Dual carrier receiver board DTPB

• Dual carrier power board DPB

• Dual carrier amplifiers board DPAB

• Dual carrier wireless carrier frequency board

DTRU MAIN FUNCTION

1.Downlink max process 2 carrier business, complete rate adaptation, channel coding, interweaving and encryption, generate TDMA burst pulse, GMSK/8PSK modulation, and complete digital conversion of two carriers.
2.Uplink max process 2 carrier business, realize 2 carriers uplink digital down conversion, receiver diversity combining, digital modulation(GMSK/8PSK demodulation, equilibrium), decode, interweave, channel code and rate adapt, send to CMB processing through HW.
3.Realize uplink and downlink RF signal processing.
4.Receive the system clock from CMB and generate the clock required by this module.
5.Implement and read various hardware management identifiers: cabinet number, slot number, single board function type, single board version, etc.
6.Complete business data and operation maintance channel communication through HW and CMB board.
7.Receive CMB’s switch electric signal, complete the up and down power of the module
8.Support software version’s updating online and loading, support programmable device version upgrade.
9.Detect the working status of the module, collect warning signals in real time and report them to the main control board CMB.
10.Support RF frequency hopping, DPCT, downlink transmite diversity and uplink 4 - way receiving diversity.
11.Support closed loop power control.
12.Provide debugging serial port, network port.
13.Board power port(-48V, -48V ground, protect ground, digital ground), it has anti-reverse connection function of power supply.
14.Slow start function and intelligent power down function
