Thales Electron Devices is offering the new TH 594 water-cooled tetrode for the high-power digital FM radio broadcast market.
The company said it is suitable for IBOC applications. It joins the TH 343 and TH 391 air-cooled tetrodes in the company’s FM product line.
The company said the TH 594 tetrode has 40 kW anode dissipation and delivers 35 kW of continuous wave (CW) power, or 60 kW peak power; it said the output power makes the TH 594 one of the most powerful FM radio broadcast tetrodes.
Features include pyrolytic graphite grids for mechanical stability and a water-cooled anode (hypervapotron technology) for a high power dissipation rating. A compact common grid cavity does not require adjustments to the neutralization circuit.
“Used with the TH 594 tetrode, this cavity enables peak power of 60 kW with a gain of 15.5 dB,” the company said.
