DIGITAL TV TRANSMITTER SCREEN SFT 301U

10.900,00

Digital, Analog and Dual Stream TV Transmitter The FUTURE SFT series is reaching the highest level of technology in both digital TV signal processing and RF domain.

Dual transmission compact / digital / analog transmitter (3RU),
UHF (bands IV and V), LD-MOS amplifier, color display,
Internal GPS / Glonass receiver, ASI and IP input, last
linear and nonlinear adaptive generation
pre-correction. Not including outlet filter and cabinet
Shelf. Air conditioning. Output Power: Digital 300 Wrms
(400 Wrms in ATSC), 500 W maximum analog sync.

This Series of TV Transmitters achieves maximum performance thanks to:

1) ARK-X: The new evolution of ARK series multi-standard DTV controllers, the ARK-X series, capable of meeting or exceeding all the requirements of international DTV broadcasters.

Improving digital adaptive pre-correction and configuration flexibility are the key points of this advanced product, developed by the excellent Digital Signage department of display R&D.

2) Latest generation LDMOS devices: stronger and more efficient compared to the past, with a special low-loss design of the mix-and-match system, together with very high efficiency power supplies (more than 96% efficient).

3) Compactness: a new concept of heatsync and ultracompact power supplies guarantees the minimum sizes of amplifier modules with air or liquid cooling systems, and a very reduced dimensioning of the cooling system itself.

TV transmitters The FUTURE SFT series is the result of Screen’s intense R&D in high-performance RF amplifiers, combined with the vastly improved new software pre-correction capability and highly efficient power supplies (> 96%) .
