MICROWAVE KLYSTRON-TYPE DEVICE Russian patent published in 2010 - IPC H01J25/02 

FIELD: electricity.

SUBSTANCE: in microwave device, output resonator includes first double-gap resonator (DGR) and second one positioned inside the first one, so that high-frequency (HF) gaps of second DGR are positioned between HF gaps od the first DGR. First DGR is set for anti-phase (AP) oscillation with frequency ω₁=ω and for in-phase (IF) oscillation with frequency ω₂=2ω, second DGR is set for AP oscillation with frequency ω₃ multiple of ω, so that ω₃>2ω, and for IF oscillation with frequency ω₄=2ω₃. Microwave energy output from first DGR is performed at ω₁ and ω₂ frequencies over first coaxial transmission line (CTL), and microwave energy output from second DGR is performed at ω₃ and ω₄ frequencies over second CTL. Third DGR set for AF oscillation with frequency ω₅ multiple of ω, where ω₅>ω₃, ω₅≠ω₄, and for IF oscillation with frequency ω₆=2ω₅ can be added into second DGR, so that and microwave energy output from third DGR is performed at ω₅ and ω₆ frequencies over third CTL. In order to improve efficiency of electron flow grouping and performance factor, at least one intermediate resonator of microwave device can include two or three DGR, where first DGR is set for AP oscillation with frequency ω₁ and for IF oscillation with frequency ω₂, second DGR is set for AP oscillation with frequency ω₃ and for IF oscillation with frequency ω₄, and third DGR is set for AF oscillation with frequency ω₅ and for IF oscillation with frequency ω₆.

EFFECT: simultaneous obtainment of microwave oscillations at microwave device output with four or more frequencies multiple of input signal frequency.
