TWTA-Qualified CW Klystron Amplifier from Canada

A continuous wave (CW) klystron designed for high-power RF amplification in satellite ground station transmitters, operating at X-band frequencies (8-12 GHz) with output power exceeding 10 kW. It falls under HTS 8540.79.10.00 as a klystron, which is a specialized microwave tube using velocity modulation for amplification in radar and communication systems. This excludes grid-controlled tubes and covers other microwave tubes explicitly named as klystrons.
