The new R&S TMU9evo air-cooled UHF medium-power transmitter represents the next step toward minimizing operating costs. 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.

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.

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.
