The new TLWH7900 series of high efficiency – wideband transmitters represents a technological leap in liquid-cooled high power UHF transmitters. The Doherty solution is wideband for the first time, so there is no longer any need for modifications or adjustments to the amplifiers when changing channels. The TLWH7900 transmitters provide the optimal solution for deploying or extending a digital broadcast network with HDTV, DTV and mobile TV channels globally. They are up to 42% energy efficient, which translates into immediate cost benefits for operators. They are equipped with state-of-the-art signal processing technology and power amplifiers based on LDMOS -50 volt. transistors characterised by high power density. They provide power-size and performance-reliability ratios that allow the signal to be transmitted with the highest quality. The compact, modular design and high power efficiency facilitate installation and maintenance, significantly reducing the total cost over the life of the transmitter for the broadcast operator.

The TLWH7900E transmitters use the asymmetrical Doherty broadband architecture with a very careful design aimed at improving energy efficiency. Its compact and modular design facilitates installation and maintenance, significantly reducing overall costs over the life of the transmitter. It allows the broadcasting of television signals in the UHF band in the main standards: DVB-T/T2, ATSC or ISDB-T/TB. They have a high energy efficiency, up to 42%. It is characterised by an efficient and silent liquid cooling system and high performance while occupying very little space. Translated with www.DeepL.com/Translator (free version)
- The new Wideband High Efficiency TLWH7800 Series represents a step ahead in the technology of high power UHF liquid cooled transmitters. For the first time the Doherty technology becomes Wideband, meaning that it is applicable to the whole UHF band. Therefore, no modifications in the amplifiers are required when the operator needs to change the RF channel. TLWH7800 Series provides the optimal solution to operators that want to deploy or extend a digital broadcast network with HDTV, DTV and mobile TV channels globally. They offer an outstanding efficiency up to 42%, enabling a high economic benefit to broadcasters. 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. They feature a power-to-size and performance-to-reliability ratios that allow the signal broadcasting with the highest quality. Its compact and modular design as well as its high energy efficiency facilitate the installation and maintenance, thus significantly reducing the total expenditures over the life of the transmitter for the broadcast operator.
