Product Overview

8-ChMPEG-2/H.264标清编码器

Gospell’s GT-5900-1600 is a medium power air-cooled UHF terrestrial DTV transmitter which combines up to four power amplifier modules with a maximum 1600W of output power. It has superior performance and enhanced efficiency by adopting a series of technologies. It can work in any frequency within the UHF span, and the transmitting bandwidth can be up to 80MHz.

This series of products has an optimized design in forced air cooling and architecture, with lower noise, higher efficiency and outstanding anti-interference performance; GT-5900-1600 series can support a wide range of Digital Terrestrial Television (DTT) standards, such as DVB-T/H, ATSC, DTMB, ISDB-T/Tb and even the latest DVB-T2 standards.

By incorporating our latest technologies of linear and non-linear digital adaptive pre-correction, RF delay and co-channel interference rejection, this system fulfills the needs of single bａnd or broadbａnd transmission in medium to large-scale terrestrial coverage scenarios.
