Manufacturers : RF and microwave electronics : Microwave tubes
Microwave tubes are comprised of a body section including a slow wave circuit or a cavity for achieving an amplification through an interaction between an electron beam and an input signal wave and a collector section for eventually capturing the electron beams. Microwave power finds extensive applications to various fields such as communication, laser, industrial heating, particle accelerators, radio astronomy, and nuclear fusion. A microwave tube such as a traveling-wave tube or a klystron is used in various fields of communication, television broadcasting, radar, industrial heating, and nuclear fusion. A beam rectilinear type microwave tube generally amplifies and oscillates a microwave using an electron beam. A linear-beam microwave tube for high power has a collector core for collecting electrons of electron beams, which turns into high temperatures and high voltages during its operation. Magnetron microwave tubes are most commonly used as high-power oscillators either in a pulsed or a continuous mode.
