The new TLWH7900E series of liquid-cooled transmitters represents a further step in high energy efficiency by offering operators a very compact solution in terms of power density, providing an optimal service for the development or extension of digital TV networks.
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.
