Effects of synchronization in a system of two coupled oscillators with time-delayed feedback are investigated. Phase space of a system with time delay is infinite-dimensional. Thus, the picture of synchronization in such systems acquires many new fea

Time-domain modeling of vacuum tubes is important for theoretical analysis of spurious oscillation, amplification and generation of short pulses and complex multifrequency, or chaotic signals. In this paper, a time-domain model of a klystron delayed

The results of computer simulation of a two-stage millimeter-wave klystron oscillator are reported. The oscillator consists of two closed-loop floating-drift-tube klystrons with the output cavity of one klystron connected to the input cavity of the o

A scheme of the generator of chaotic oscillations in the microwave band is proposed that is based on two drift klystrons coupled in a ring circuit. The first klystron doubles the frequency of the input signal and the second klystron mixes the second

A method to suppress self-modulationory in the self-oscillatory systems with delayed feedback (DF) is proposed. The method is based on an additional DF circuit whose parameters are chosen in such a way that the signal components at the fundamental an
