Crossed-field microwave tubes
Abstract
The basic principles of crossed-field microwave tubes are outlined noting space harmonics, electron interactions, tube operation, forward-wave amplification, backward-wave amplification, and voltage tuning. Attention is given to the design and operation of the M-type backward-wave oscillator which is applicable in barrage and spot noise jamming by frequency and/or amplitude modulation. The backward-wave locked-oscillator or amplifier is described with reference to the high-power problem, the effects of insertion loss, operating modes, and a medium-power S-band system. The voltage-tunable magnetron oscillator, consisting of a tube subassembly, RF circuit, and magnet is reported noting applications in the countermeasures field such as local oscillators, drivers, and output tubes.
