Abstract. The paper presents the results of computer simulation and experimental study of a miniature multi-beam pulse klystron operating in the Ku-frequency range with modified designs of the input and output resonance systems. The use of three-link filter systems at the input and output of the device, made on the basis of two single-gap cavities, inductively interconnected through a connection slit and a passive cavity, made in the energy output, allows to increase the output power of the device and increase the working band by 2-3 times compared to conventional designs of input and output resonance systems of multi-beam klystron, made on single-gap cavities. The parameters of the coupled resonator system were calculated using the Ansoft HFSS program. The distribution of the electric field on the working modes of oscillations is investigated. The main electrodinamical and electronic parameters of various modes are investigated ( coupling coefficient Ì, relative active electron conductance Ge/G0, quality Q and accelerating potential U0 = 3 kV). Found operating conditions, which provide effective interaction of multi-electron beam with a high-frequency electromagnetic field. The possibility of further enhancing the output parameters of low voltage miniature multi-beam Ku-band klystrons is shown.

Key words: klystron, filter system, cavity, bandwidth.
