1000w SFN and MFN Broadcast Dvb-t and Dvb-t2 Transmitter
Medium Power UHF Terrestrial DTV Transmitter
Overview:
Dibsys’DTT-5900-1000 is a medium power air-cooled UHF terrestrial DTV transmitter
which combines up to four power amplifier modules with a maximum 1000W 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;
DTT-5900-1000 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.
Key features:
- High Performance Supports up to 1000W of digital output power Optimized structure design, with lower noise, higher efficiency and outstanding anti-interference performance
- High Flexibility and Stability Modular design across the whole system, easy installation, maintenance and upgrade
Multiple protection mechanisms are introduced for over-load, over-temperature, over-current and high VSWR
Large and dynamic Auto Gain Control (AGC) circuit ensures stability of output power
Improved power efficiency thanks to linear and non-linear Digital Adaptive Pre-correction - High Adaptability and Availability Suitable for different contries and/or areas because multiple DTT standards are complied with, including DVB-T, DVB-T2, ATSC, DTMB and ISDB-T/Tb Available in single and three phase power grid environments to meet different requirements of deploymentWide range of working frequency from 470MHz to 860MHz
- Lower CAPEX/OPEX Improved ratio of cost to performance, lower CAPEX for operatorsLow power consumption with high efficient LDMOSamplifiers to reduce electricity cost for operatorsReduced investment in manpower, benefits from convenient local monitoring and management through built-in touch screen display or remote monitoring via SNMP network management and/or telcom wireless network
- User Friendly Monitoring Interface Built-in color TFT LCD with touch screen in the front panel, supports monitoring & control of working statesand any malfunction on any module without additional testing/monitoring equipment required, such as transmitting power, VSWR, working voltage/current, fan speed, IP address and so on.
