21023150761079005015 GSM Micro Cellular Base Station Huawei BTS3012 DTRU M900

[Product Description]

DTRU M900

· Radio frequency transmitting part, completed two carrier modulation, baseband signal to RF signal up conversion, filtering, frequency hopping radio frequency, signal amplification, combining output function.

· The RF receiver, RF signal shunt, completed two carrier, radio frequency hopping diversity reception and demodulation function.

· Baseband processing part, the completion of signaling processing, channel coding, interleaving inverse interlacing, modulation and demodulation functions.

· Supports a variety of data service, Phase II provisions GPRS business, EDGE business support.

· Support transmit diversity, 4 receive diversity control functions.

· Support launch he Lu, the phase and frequency of power synthesis (PBT) function.

· The baseband and RF unit DBRU is the main function modules of DTRU, baseband signal and radio frequency signal modulation and demodulation, data processing, combined shunt and other functions.

· The power amplification unit DPAU will output DBRU signal amplifier to the power level required, to support the launch of broadband combiner, PBT function.

· Double density frequency power supply DTPS is in the DTRU module power supply board. -48V DC power input to the DTRU, converted to +28V output power in DTPS single board, for the use of DPAU.
