GQ-3640
 
QAM-to-QAM Regenerative Repeater
 
   GQ-3640 is a QAM-to-QAM regenerative repeater with frequency shifting option. It can receive 2 DVB-C signal from its RF inputs, for demodulating, TS passing through, channel coding and finally output 1^[1] QAM signals at adjacent channels. GQ-3640 can be used in the reginal edge headend systems, to improve RF signal quality from the succeeding system and perform QAM frequency shifting according to regioanl network needs, for ensuring signal quality and stability in long distance transmission.
