R&S^®NV8600 UHF Transmitter Family

The R&S® NV8600 transmitter family represents a new generation of liquid-cooled UHF transmitters for digital TV (DVB-T/-H, ATSC). The transmitters include the following main components:

• Exciter
• Power amplifier incl. power supply unit
• Transmitter rack

The UHF transmitter are available for DVB-T/-H with powewrs from 1.3 kW to 11.8 kW, and for ATSC with powers from 1.8 kW to 16.5 kW (higher power ratings on request). Each amplifier has its own power supply unit that is integrated in the amplifier module and thus cooled by the liquid cooling system.

The amplifier power supply units are fed directly by the AC supply voltage, additionally increasing the availability of the transmitters. Parts exclusively made of stainless steel, aluminium, or plastic are used for the cooling system in the transmitter rack. The amplifier module is self-engaging and can be exchanged during operation, without liquid escaping from the closed cooling system and without impairing the operation of the other modules. A second exciter (standby) and an automatic switchover unit can be integrated into all transmitters.
