High-power FM transmitter
The liquid-cooled R&S THR9 high-power FM transmitter provides output power ranging from 5kW to 40kW. It is digital-ready, making it well equipped to meet future demands because it supports both FM and digital standards in VHF band II such as HD Radio. Network operators will benefit from the MultiTX concept, integrating multiple transmitters into a single rack. The THR9 concept makes it possible to accommodate as many as four 10kW transmitters in a single rack. The FM transmitter is highly efficient: Two RF power components ? the power combiner and the RF rigid line ? have minimum attenuation. This enables efficiency values of up to 75 percent in analog FM mode and cuts energy costs by as much as 50 percent.
