| 總結: | Title screen We present the results of studying a cascade microwave switch capable of stable operation at the power level of a regular waveguide. The cascade stage is formed by connecting several identical H-joints in the side branch of the tee of a conventional microwave interference switch. The connection distributes the power of the switched wave between the joints and varies the level of the switched power. The method of the scattering matrix is used to analyze the properties of such a switch based on H-joints with different matching levels of the side branch. It is shown that the cascade of sufficiently well-matched joints can decrease the level of the switched power by several times and ensure a higher operating power and a better stability of the switching, while the cascade with coupling worse than a certain boundary value can increase the power of the switched mode by several times and ensure switching of a lower-power mode. The numerical criterion of the coupling quality is found, which divides operation of the switch with increased and decreased switched powers. It is also found that in the switch under consideration, the microwave energy is distributed between the cascade elements in the process of the switching, which can affect greatly both the switching process and the characteristics of the switched mode during the process. The results of the analysis are compared with the experimental data at high and low power levels. Режим доступа: по договору с организацией-держателем ресурса |
