CTK 35-2 High Frequency Metal-Ceramic Power Triode

The CTK 35-2 is a power triode manufactured by Thomson / Thales. Top-of-range Thales CTK series coaxial metal-ceramic triode delivering 110 kW at up to 100 MHz with water-cooled anode for the most demanding industrial CO₂ laser and RF heating applications.

Key ratings of the CTK 35-2 include tube type Triode, max output power 110 kW, max frequency 100 MHz, filament voltage 9 V, filament current 360 A and weight 10 kg.

Typical applications are high-power CO₂ laser cutting oscillators, large-scale RF induction heating, high-power RF amplifiers, industrial welding systems and heavy-duty RF generators. Notable features: 110 kW maximum output, top-power CTK series triode, water-cooled anode and 100 MHz capable.

Power triodes are three-electrode grid tubes used as RF oscillators and amplifiers in industrial RF heating (plastic welding, induction heating, drying), RF-excited CO₂ lasers, broadcast transmitters and particle accelerators. In oscillator service they work with vacuum capacitors in the tank and matching circuits.
