Abstract
Findings in the research on conditions for occurrence of a multipactor discharge in coaxial switches have been presented. A model of a powerful coaxial microwave SPDT switch operating in the frequency range below 1.7 GHz has been obtained. Calculated values of the electrical parameters have been given and the possibility of manufacturing a coaxial switch for spacecraft with an operating power margin has been shown. The manufactured prototype of the microwave switch can withstand at least 400 W of RF power at a frequency of 1 GHz, which has been confirmed by the experiment.
