Broadband 300W UHF digital tv broadcast isdb-t transmitter

Dibsys DTT5900-300 series is an indoor UHF Digital Terrestrial Television (DTT) transmitter/gap filler with up to 300W of output power, and is designed for small-scale or blind area coverage application in DTT broadcasting.

Dibsys DTT5900-300 series utilizes the state-of-the-art LDMOS devices and compact 4U rack-mount structure that enables DTT operators to have reduced energy cost and with much less occupied space of equipment in their DTT network. This series supports various DTT modulation standards, such as DVB-T/H, DVB-T2, DTMB, ATSC, ISDB-T/Tb, and also can operate in SFN mode enabling less spectrum resource is used.

Dibsys DTT5900-300 series incorporates multiple self-protected mechanisms, including high VSWR, over-temperature, over drive, over current, over voltage and under voltage. It supports Web based management and maintenance for remote status monitoring and controls, this can significantly reduce management time and operating expense (OPEX). By incorporating the latest technologies of RF delay and co-channel interference rejection, this system fulfills the needs for DTT coverage of SD and HD digital television programs. This is especially suitable for small-scale coverage and gap filling with complex terrains.
