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 low energy consumption, less maintenance and reduced rental costs over the entire system lifetime.

The liquid-cooled transmitters deliver FM output power of up to 40 kW per rack. The integration versatility ranges from single transmitters with built-in pump unit and space for additional system components to multitransmitter systems and even N+1 configurations in a single rack. By making it possible to integrate high output power and multiple transmitters, Rohde & Schwarz offers the highest power density per rack.

The R&S®THR9 transmitter family for band II attains efficiency values of up to 75 % in analog FM mode, which equates to significant energy savings compared with air-cooled systems that often have complex cooling infrastructures. The R&S®THR9 transmitter family is configured for digital modulation in band II and can generate hybrid signals as defined in the HD Radio™ standard, as well as purely digital signals.
