TUWH4000E series

Wideband Asymetric High Efficiency Technology, Air cooled system

The new High Efficiency TUWH4000E Series represents a step ahead in the technology of high power UHF air cooled transmitters. The series employs asymmetric ultrawideband Doherty technology, covering with only one model of amplifier from 470 to 700 MHz. Therefore, no modifications in the amplifiers are required when the operator needs to change the RF channel inside this UHF band..

The TUWH4000E transmitters features a market-leading energy efficiency, offering an efficiency up to 45% and providing broadcasters with a high economic benefit.

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 strat-up 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
