Research of Electrodynamic Parameters of the Two-Gap Quasi-Fractal Resonator for a Small-Sized Multi-Beam Klystron

摘要

The purpose of this work is research of a possibility of tuning the two-gap resonator with the strip quasi-fractal inductive elements executed on a dielectric substrate for two multiple frequencies. The main electrodinamic parameters of various modes are investigated (resonance frequency, characteristic wave impedance ρ=R/Q, quality Q). The possibility of tuning of resonant system for multiple resonant frequencies was studied that can be used in a klystron buncher for increasing efficiency and also in the frequency multiplier. This cavity was designed for application in low-voltage dual-frequency klystrons. Such a klystron can be used in on-board transmitters of radio systems for various purposes (radar, transponders, navigation, communications).
