Rohde & Schwarz Will Demonstrate THR9 FM/HD Transmitter at Radio Show

Will exhibit new high-power transmitter this week in Austin September 5, 2017

AUSTIN, Texas — Transmitter, test and measurement, and studio equipment manufacturer Rohde & Schwarz will exhibit their THR9 high-power transmitter at the 2017 Radio Show (Booth 305) this week in Austin. It’s an FM or FM + HD transmitter with 100% liquid cooling, and obtains up to 75% efficiency (in analog FM mode).

The THR9 supports Generation 4 HD Radio technology as well as purely digital standards in band II (for DAB). New exporter and importer functions, now in a 1RU form factor, simplify the system architecture of HD Radio transmitters. The THR9 HDR900 hardware is based on FPGA signal processing instead of PC-based solutions, and, according to R&S “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 optimize efficiency with low service costs.

The R&S THR9 has a power density per rack of up to 40 kW in analog FM mode (or 24 kW in hybrid mode). Other components and transmitters can be installed in the rack as well, which further reduces space requirements. The R&S THR9 includes support for asymmetrical sidebands for HD Radio, as well.
