an electron tube used to generate or amplify electromagnetic radiation in the microwave region by velocity modulation
an electron tube used to amplify microwave-frequency electromagnetic radiation.
A klystron is a specialized linear-beam vacuum tube, invented in 1937 by American electrical engineers Russel and Sigurd Varian, which is used as an amplifier for high frequencies, from UHF radio frequencies up into the microwave range. Low-power klystrons are used as local oscillators in superheterodyne radar receivers, while high-power klystrons are used as output tubes in UHF television transmitters, microwave relay, satellite communication, and radar transmitters, and to generate the drive power for modern particle accelerators. Klystron amplifiers have the advantage of coherently amplifying a reference signal so its output may be precisely controlled in amplitude, frequency and phase. Many klystrons use waveguides for coupling microwave energy into and out of the device, although it is also quite common for lower power and lower frequency klystrons to use coaxial cable couplings instead. In some cases a coupling probe is used to couple the microwave energy from a klystron into a separate external waveguide. All modern klystrons are amplifiers, since reflex klystrons, which were used as oscillators in the past, have been surpassed by alternative technologies.
