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.
