SUPERPOWER MILLIMETER WAVE TUBE.
Abstract
Experiments were performed on the frequency locking of magnetrons using both reciprocal (special waveguide tee junctions) and non-reciprocal (circulators) coupling techniques. The results presented include the locking of a single magnetron having a second-order output circuit with circulator coupling and a three-tube array with reciprocal coupling that gave a 15-decibel gain and 600kilowatt output at X-band. Packaged magnetrons were used in these experiments without any modifications, and thus the results are intended to demonstrate the principles involved without implying that they represent optimized performance. An equivalent-circuit model whose parameters were experimentally determined is presented. The good quantitative agreement between the performance predicted by the model and all of the experimental results is shown. Multimagnetron arrays were designed by an active filter theory. Computer programs were developed for predicting the matched and mismatched load performance and the self-oscillating modes of these arrays. In addition to the arrays actually built and tested, other arrays were designed and evaluated on the computer to demonstrate some significant aspects of magnetron locking. (Author)
