CTK15-2 Triode

The CTK15-2 is a robust, high-frequency metal-ceramic transmitting triode meticulously engineered for demanding industrial RF applications, particularly RF oscillation and Rofin-Coherant Laser DC Resonators.

Designed for continuous wave (CW) or pulse mode operation, this water-cooled tube delivers a substantial continuous RF output power of 45KW. Its coaxial design, coupled with advanced metal-ceramic technology, ensures reliable performance and longevity. 

The CTK15-2 features a reticular formation thoriated tungsten cathode and pyrolytic graphite grid, contributing to its high efficiency and stable operation up to a maximum frequency of 120 MHz. This powerful triode is an ideal component for industrial systems requiring consistent and high-power RF energy.
