About the CTK 12-1

The CTK 12-1 is a power triode manufactured by Thomson / Thales. Thales high-µ coaxial metal-ceramic power triode with 30 kW RF output for industrial RF heating and CO₂ laser oscillator applications.

Key ratings of the CTK 12-1 include tube type Triode, output power 30 kW, max frequency 120 MHz, construction Metal-ceramic coaxial, cooling Forced air and cathode Thorium tungsten.

Typical applications are industrial RF heating, CO₂ laser oscillators, plastic welding, wood gluing systems and RF power amplifiers. Notable features: 30 kW RF output, high-µ triode design, metal-ceramic coaxial and thorium tungsten cathode.

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.
