High Power UHF TV Transmitters

Wideband Asymmetric High Efficiency Technology, Liquid cooling system.


The new TLWH7900E liquid cooled transmitter series represents a step ahead in energy efficiency optimization, giving today’s broadcasters a space a space-saving and cost-efficient solution and providing an ideal service for the development or extending digital TV networks.

The series employs asymmetric ultrawideband Doherty technology with a very careful design oriented to enhance power efficiency. Its compact and modular design facilitates the installation and maintenance tasks and the automatic efficiency optimization system.

They enable broadcast television signals in the UHF frequency range, under many standards, DVB-T/T2/H, ATSC or ISDB-T/TB and offer an outstanding efficiency up to 42%.

Transmitters present an efficient and silent liquid cooling system with high performance and occupying very little space.
