Rohde & Schwarz Intros Liquid-Cooled TX

TH9 can scale up to 40 kW in a small footprint

Transmitter maker Rohde & Schwarz has a new liquid-cooled high-power FM transmitter available, the THR9.

The THR9 ranges from 5 kW to 40 kW. It is digital ready.

The THR9 is compatible with R&S’ Multi-TX design. “MultiTX involves integrating multiple transmitters into a single rack. In combination with the liquid-cooling system, this helps reduce the amount of space required,” a release explains. It adds that a single THR9 rack can as many as four 10 kW transmitters.

The release says that a liquid cooling system can reduce space requirements by as much as 40% compared to conventional air cooling systems or more with multiple transmitters using the MultiTX configuration. It explains, “The cooling system of the R&S THR9 has two pump modules in active standby and a heat exchanger equipped with two redundant fans. This design ensures high availability of the transmitter cooling system.”

The THR9 supports dual-drive configurations, N+1 configurations or a combination of the two. System configurations of up to 3+1 are possible in a single THR9 rack. Internal components are designed to be energy-efficient.
