Abstract. The results of numerical simulation of the output characteristics of
a miniature four-beam klystrode designed for operation in the frequency range
200-700 MHz with continuous output power of about 300 W in-band gain of 8 MHz
are described. The results of experimental studies of the layout of the output
two-mode double-gap resonator on the PCB are given. The possibility of
independent tuning of the resonator simultaneously in-phase and anti-phase modes
of oscillations, the frequencies of which correspond to the first and third
harmonics of the input signal, is shown. The usage of single-stage recovery
allows to increase technical efficiency to about 70%. The device can be used instead of the
microwave tetrodes in phased array radar UHF.
Key words: multibeam klystrode, numerical
