GT-5900-500 - Gospell Digital Technology Co., Ltd.

Main Features

• 470 to 860MHz

• Compact structure, supporting up to 500W digital output power

• Linear & non-linear digital pre-correction function in exciter

• Modular design across the whole system, easy installation, maintenance and/or upgrade

• Low power consumption with high efficient LDMOS amplifiers to reduce electricity costs for operators

• Suitable for different countries and/or areas because multiple DTT standards are complied with, including DVB-T/H, DTMB, ATSC, ISDB-T/Tb and DVB-T2

• Low power consumption with linear design, further improves transmitting power and minimizes non-linear distortion, to satisfy transmission requirements of single band and broadband

Product Overview

8-ChMPEG-2/H.264标清编码器

Gospell’s GT-5900-500 Series is a low power UHF terrestrial DTV transmitter, which inherits the high performance, high stability and high reliability of Gospell’s many products. It can work in any frequency within UHF span, and the transmitting bandwidth is up to 80MHz. By incorporating our latest technologies of linear and non-linear digital adaptive pre-correction, RF delay and co-channel interference rejection, this system can fulfill the needs of single band or broadband transmission in small to medium-scale terrestrial coverage scenarios.

This series of products, which has advance design and simplified architecture are small in size, with the advantage of lower noise, higher efficiency, and outstanding anti-interference performance. They support DVB-T/H, DTMB, ATSC, ISDB-T/Tb and DVB-T2 standards, thus having greater flexibility and suitability in actual deployment.
