The next level in operating cost savings – the new high-power transmitter from Rohde & Schwarz


Rohde & Schwarz is committed to making network operatorsʹ lives easier. Over the years, the company has incorporated innovative ideas and concepts into transmitter development, and the new R&S THU9evo liquid-cooled UHF high-power transmitter represents the next step toward minimizing operating costs. Rohde & Schwarz was able to leverage its many years of experience in Doherty technology, which is the key to the new transmitter’s improved efficiency: up to 40 percent for COFDM standards and up to 43 percent for ATSC. The result is a reduction in energy consumption, which in turn lowers network operator costs. The transmitter delivers output powers from 1.5 kW to 96.5 kW for COFDM and from 1.65 kW to 106 kW for ATSC. At 17.4 kW (COFDM) and 19 kW (ATSC) per rack, it offers the highest power density on the market, which translates into enormous space savings.

The new R&S Efficiency Optimization feature minimizes energy costs for all types of operating scenarios. This feature proves its worth especially when adjusting output power or during channel changes. An intelligent algorithm, deployed at the press of a button or adaptively, optimizes amplifier parameters so that the transmitter achieves maximum energy efficiency at all times, resulting in the most economical system operation for every scenario.

The new R&S PHU903 high-power amplifier is the key to the excellent system efficiency. Unmatched by any other amplifier on the market, the R&S PHU903 provides maximum efficiency, combined with the capability to operate across the entire UHF range without any modifications. This is made possible by the R&S Multiband Doherty technology, which has been even further improved by Rohde & Schwarz. This technology ensures that network operators are optimally prepared for 700 MHz spectrum clearance and reallocation.

The new transmitter carries forward all of the proven strengths of the market-leading R&S THU9 platform. The R&S THU9evo retains the successful and proven R&S MultiTX concept along with the R&S Tx9 generation’s intuitive GUI, which is closely aligned with user requirements and work habits.
