AMPLIFYING KLYSTRON FOR COMMUNICATION SYSTEM Russian patent published in 1995 - IPC

FIELD: communication, electronics. SUBSTANCE: klystron includes electron gun, input resonator, intermediate resonators of basic frequency, drift tubes and collector. Double frequency resonator placed in front of output resonator at distance 0.05-0.6 length of drift tube is tuned to frequency chosen within interval 2 (F_o+Δf_р)≅ f₁₁≅ 2(F_o+2Δf_р), where F_o is central frequency of working range of klystron; Δf_р is width of working range of frequencies of klystron. Incorporation of double frequency resonator diminishes level of combination components in spectrum of output signal of klystron working under mode of simultaneous amplification of two and more HF signals located in one working frequency range. EFFECT: diminished content of noises in transmitted signal. 3 dwg
