TLWH7900E
 

The TLWH7900E series of liquid-cooled transmitters represents a significant advance in power efficiency for digital TV networks. Featuring high-efficiency wideband asymmetric Doherty technology, these transmitters offer a very compact solution in terms of power density, allowing operators to optimize the development or expansion of digital TV networks.

The liquid-cooled system, in addition to being highly efficient, is silent and ensures optimal performance with reduced power consumption, reaching up to 42% energy efficiency. This series allows the transmission of signals in the UHF band and is compatible with the main digital television standards such as DVB-T/T2, ATSC and ISDB-T/TB.

Its modular and compact design facilitates installation and maintenance, significantly reducing operating costs throughout the life of the transmitter. Thanks to these features, the TLWH7900E offers a reliable and high-performance solution, taking up very little space and providing efficient and economical operation.

Key features:

  • High energy efficiency inside UHF band (470 to 700 MHz) with no tuning of adjustments
  • Values up to 42% for COFDM (cooling included)
  • Automatic efficiency optimization
  • Hot-pluggable power amplifiers (2U) based on LDMOS-50 volt, asymmetric ultrawideband Doherty technology
  • Compact design for easy installation in confined spaces
  • Liquid cooling system to dissipate heat efficiently and noiseless
  • “Output channel” and “Impulse channel response” show via web server
  • Digital Adaptive Precorrection
  • High redundancy to ensure máximum reliability. N+1 redundancy ready
  • Multiple options for local operation: through the display of the exciter/Control Unit or Web Server
  • Wide range of possibilities for remote monitoring: dry contacts and SNMP/ Web Server
  • Standalone Control unit module with front panel LCD Display included for measurement / configuration
