Medium power UHF TV Trasnmitters 

Wideband High Efficiency Technology, Air cooling system.

Discover WHET Series

The new medium power Wideband High Efficiency TUWH3000 series represents a step ahead in the technology of UHF air cooled Transmitters. The Wideband-Doherty technology is applicable to the whole UHF band, therefore, no modifications in the amplifiers are required when the operator needs to change the RF channel.

The new Transmitters features a market-leading energy efficiency. They offer an efficiency up to 42%, providing broadcasters with a high economic benefit.

They are equipped with the most advanced technology in signal processing and the power amplifiers are based on LDMOS transistors-50 volt. characterized by a high power density.

The customer oriented and extremely compact design provides full flexibility and multiple configurations per rack, saving a lot of space in the transmitter site. The rapid and easy stratup of the transmitter and the power of the Web Server ensures fast commissioning and easy operation. The different options for redundancy and optimal design of critical modules guarantee continuity of service throughout the life of the transmitter.

Key features
  • High energy efficiency over the whole UHF band to minimize consumption and OPEX. Values up to 38% for COFDM waveforms and 42% for ATSC.
  • Compact design: up to 300 Wrms in only 3RU (1U Exciter – 2U Amplifier)
  • Power amplifiers based on LDMOS-50 volt. technology with high power density.
  • Possibility of integrating several transmitters with Dual Drive or N+1 redundancy in a single cabinet.
  • Digital modulations: (DVB-T/H/T2, ISDB-T/TB, ATSC).
  • Frequencies: from 470 MHz to 800 MHz.
  • Digital Adaptive Precorrection.
  • High redundancy to ensure maximum reliability.
  • N+1 redundancy ready with CCU9000.
  • Multiple options for local operation: throughthe display of the exciter, a Control Unit or Web Server (opt.).
  • Wide range of possibilities for remote monitoring: dry contacts and SNMP / Web Server (opt.).
