The next level in operating cost savings – the new medium-power transmitter from Rohde & Schwarz at IBC 2018

The R&S TMU9evo UHF transmitter from Rohde & Schwarz represents the next level of development for the company’s successful family of medium-power transmitters. The new transmitter comes with further improvements in both energy efficiency and reliabilty, allowing network operators to achieve even greater operating cost savings. The R&S TMU9evo delivers maximum energy savings even during channel changes or when adjusting the output power. The intelligent R&S Efficiency Optimization feature automatically provides the most economical operation possible for every operating scenario.

Rohde & Schwarz is committed to making network operators’ lives easier. Over the years, the company has incorporated innovative ideas and concepts into transmitter development, and the new R&S TMU9evo air-cooled UHF medium-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 top efficiency and unrivaled reliability. The result is a reduction in network operator costs and an increase of operational convenience.

Featuring high-quality RF components and designed for long life, the transmitter provides utmost reliability and signal quality. Plus, the R&S TMU9evo is the only transmitter in its power class that can be optionally equipped with an integrated exciter backup battery, enabling it to dependably bridge power interruptions of up to 10 seconds. This reduces off-air time to a minimum and eliminates the need for an uninterruptible power supply (UPS).

The 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 R&S PMU905 medium-power amplifier is the key to the excellent system efficiency. Unmatched by any other air-cooled amplifier on the market, the R&S PMU905 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 TMU9 platform. The R&S TMU9evo 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. Furthermore, it is perfectly prepared for future requirements like new digital broadcast standards such as ATSC 3.0.

The R&S TMU9evo air-cooled UHF medium-power transmitter delivers output powers from 400 W to 3.0 kW for COFDM and ATSC. The new transmitter, which will be available from Rohde & Schwarz as of November 2018, will be showcased at IBC in hall 7, booth 21.
