Product Overview


GQ-3800B is a single-channel DVB-T2 modulator. It has two ASI inputs (MPEG-2 TS or MI data), and provides two IP signal input interfaces for DVB-T2 SFN/MFN. It can receive signal in both standard TS format and T2-MI format, and outputs one DVB-T2 (30MHz~900MHz) modulated signal after channel coding, interleaving and modulation. It operating parameters can be configured locally or remotely via DVB-T2 gateway. GQ-3800B’s output signal can be directly connected with power amplifier to constitute a digital terrestrial transmitting station.



Main Features:


  • Support both SFN/MFN
  • Support Multiple Input Single Output (MISO) AND Single Input Single Output (SISO)
  • Support linear/non-linear pre-distortion correction
  • Able to work in QPSK/16QAM/64QAM/256QAM(standard or rotated) mode
  • Two ASI input interfaces can back up each other
  • Support data input in T2-MI or MPEG2 TS format
  • High-quality output, MER>42dB, shoulder level>55dB
  • Output signal bandwidth: 5M,6M,7M,8MHz
  • RF frequency range: 470MHz~862MHz, with output on/off switch
  • Main output level up to 0dBm
  • Support PAPR adjustment for output signal
  • -20dB RF testing output
  • Modulation module is designed based on FPGA to ensure the stability of device
  • Adopt extra-large cache memory for both uniform and burst input stream at ASI interface
  • Self-adaptive filter circuit design ensures outstanding out-of-band rejection
  • Support online upgrade of embedded program
