The paper represents an approval of recently published by the authors of this article nonlinear theory of cascade magnetron frequency multipliers with two electron streams. Graphs of dependencies between electronic efficiency and electrical length of the device on a height of interaction space of the first cascade at different values of interaction impedances of the first and second slowwave systems are given. Comparison of the gains of two frequency multipliers – with stepped interaction space and with smooth one – having identical constructions at fixed ratio of permanent currents and different interaction impedances is carried out. Analysis of twocascade two electron stream magnetron frequency multiplier with programmed interaction space in the output cascade has shown that devices of that type possess high output characteristics: increase in a gain in comparison with non-programmed identical frequency multiplier reaches up to 20 dB at electronic efficiency adjacent to 70-80%.
