Key facts
The R&S®THU9evo UHF high-power transmitter family heralds the next step towards minimizing operating costs for terrestrial broadcasting. Its overall energy efficiency values of up to 40 % for COFDM and 43 % for ATSC represent all-time highs. The R&S®THU9evo carries forward all the proven strengths of the R&S®THU9 platform. Network operators benefit from low operating costs throughout the product lifecycle.
R&S®THU9evo transmitters achieve an energy efficiency of up to 43 % (including the cooling system), once again setting the benchmark in their class. Years of experience and continuous development have given Rohde & Schwarz complete mastery over Doherty technology, which the company has been able to utilize to the greatest advantage.
R&S®THU9evo transmitter systems offer maximum power density and can accommodate multiple transmitters in a single rack. This significantly reduces the footprint of the Rohde & Schwarz solution compared with conventional transmitters, allowing operators to substantially reduce site space requirements and rental costs.
Thousands of R&S®THU9 transmitters are in operation around the world. Every day, they are proving that they deliver the highest reliability. This exceptional success clearly demonstrates how the Rohde & Schwarz high-power transmitter platform meets the needs of network operators, both in term of minimizing operation costs and maximizing availability.
The R&S®THU9evo amplifiers' power supplies and first-stage combiners are liquid cooled. This maximizes lifetime and reliability. It minimizes the amount of heat dissipated into the operating room and reduces air-conditioning costs.
The intelligent efficiency optimization maximizes efficiency in changing environments, either at the press of a button or adaptively. When changing channels or adjusting the transmitter power, efficiency optimization ensures that energy costs are minimized at all times.
In contrast to conventional couplers, the R&S®THU9evo low-loss power combiner is plugging directly into the amplifiers and it comes with integrated coolant distribution. Fewer RF interconnections and the elimination of interconnecting cooling hoses maximizes efficiency and reliability.
The Rohde & Schwarz exciter solution relies on a pure software based approach that ideally prepares network operators for ATSC 3.0. Based on a high-performance IT server, it enables network operator to optimally leverage the full capabilities of the standard and to flexibly respond to future signal processing requirements.
The R&S®THU9evo tracks its performance with built-in analysis capabilities such as efficiency measurement and integrated signal analysis. These features offer instant feedback on operational parameters through a self-monitoring function. This ensures a consistently high quality of service and minimal operational costs.
