Rohde & Schwarz Showcases Liquid Cooled HD Radio Transmitter at 2017 Radio Show

Premier transmitter, test and measurement, and studio equipment manufacturer Rohde & Schwarz will highlight the R&S THR9 high-power transmitter at the 2017 Radio Show (Booth 305) next month in Austin, Texas. The only HD Radio™ transmitter with 100 percent liquid cooling technology, the R&S THR9 attains efficiency values of up to 75 percent in analog FM mode.

The THR9 supports Generation 4 HD Radio technology as well as purely digital standards in band II. New exporter and importer functions, now in 1 RU, greatly simplify the system architecture of HD Radio transmitters. Based on FPGA signal processing instead of PC-based solutions, the R&S THR9 with HDR900 hardware delivers better performance and greater accuracy, which is important for consistent set diversity delay.

With its redundant liquid cooling technology, the R&S THR9 eliminates the need for high-performance air conditioning systems. All transmitter components are liquid cooled, including power supplies and couplers, and the pump and heat exchanger are matched to the transmitter to deliver superior efficiency with low service costs.

The R&S THR9 delivers the highest power density per rack of any FM transmitter manufacturer, providing up to 40 kW in analog FM mode (or 24 kW in hybrid mode) in a single rack. Other components and transmitters can be installed in the rack as well, which further reduces space requirements. Plus, the R&S THR9 includes support for asymmetrical sidebands to maximize coverage.

“Rohde & Schwarz is making sure FM radio stations are equipped for the digital future with our powerful and space-saving transmitters,” explained Erik Balladares, vice president of Broadcast & Media, Rohde & Schwarz USA. “The NAB and RAB’s Radio Show is a great opportunity to showcase our advanced HD Radio technology and explain how our liquid cooling technology reduces maintenance costs and monthly power bills.”
