WAVEGUIDE, WAVEGUIDE CIRCUITS AND ANTENNA RESEARCH STUDY.
Abstract
A study of the measuring system was made using a Hewlett-Packard 851A/8551A Spectrum Analyzer. It was found that under certain conditions a high frequency modulation was present in the output of the stabilized klystron and further that the Dymec stabilizer often locked onto one of the modulation side bands. The largest single loss within the beam waveguide resonator was due to the coupling holes. When the coupling hole loss was accounted for, using an analysis by McCumber, the measured and predicted Q of the beam waveguide resonator operating at 35 GHz were in reasonable agreement. The additional measurements made on the parallel plane resonator indicated that the coupling hole loss was also an important factor in determining the Q. The coupling hole loss cannot be accounted for in the case of the parallel plane resonator since the field distribution within the resonator is not known. It also appears that the Q of the parallel plane resonator depends on the diameter of the end plates. (Author)
