THALNA Air Cooled Transmitters

THALNA is the result of years long research in terms of size reduction and structural simplicity. The line perfectly meets the needs of customers that require medium power solutions.

The qualities of compactness and redundancy have been applied to the transmitter design as well as of the cooling system.

The new line maintains the traditional safety features of Itelco transmitters.

The architecture is built around the MEX-II exciter, which receives the signal from the studio and modulates it according to the selected standard. The signal is then distributed by an RF splitter to the inputs of the amplifier modules, whose outputs are recombined by a passive combiner before reaching the antenna: the number of modules sets the overall power without changing the control logic.

The Central Control Unit (CCU) coordinates the system, acting as a hierarchical concentrator and as the arbiter for redundancy. In Dual Exciter configurations both exciters receive the signal, but only one is routed to amplification through a coaxial switch while the other stands by on a dummy load, ensuring continuity of service. The mains distribution and the two-blower air cooling system complete the setup.
