Key facts

  • Energy efficiency values of up to 75 %
  • Analog FM or HD Radio (band 2)
  • Extreme low footprint for operational cost savings
  • Liquid cooled
  • Up to 80kW 

Highest efficiency, smallest footprint

The R&S®THR9 high-power FM transmitter family makes terrestrial broadcasting of audio broadcast signals extremely efficient and also saves space. These high-power transmitters feature an energy efficiency of up to 75 %. Liquid cooling and the integration of multiple transmitters in a single rack minimize space requirements. Audio broadcast network operators benefit from extremely low energy costs, maximum robustness and minimum maintenance expenses over the entire system lifetime.
The liquid-cooled transmitters deliver FM output power of up to 40 kW per rack and up to 80 kW in two racks. The integration versatility ranges from single transmitters with built-in pump unit and space for additio

Features & benefits

Maximum energy cost savings

R&S®THR9 transmitters achieve an energy efficiency of up to 75 % (including the cooling system), once again setting the benchmark in their class. Years of experience and continual development have given Rohde & Schwarz complete mastery over Doherty technology, which the company has been able to utilize to the greatest advantage.

Minimal footprint

R&S®THR9 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 the space required and site rental costs.

Pure liquid cooling

The R&S®THR9 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.

HD Radio

The THR9 with HD Radio™ Generation 4 is state of the art. It achieves substantially better crest factor reduction than 3rd-generation IBOC transmitters, maximizing energy efficiency and increasing HD Radio™ output power.
This means safety of investment and low cost of ownership, since they can switch from FM to HD Radio™ mode or subsequently increase the injection level using existing hardware.
