| Summary: | Заглавие с экрана Исследованы две схемы каскадного соединения интерференционных СВЧ-переключателей на основе волноводных Н -тройников - с последовательным включением тройников в боковое плечо или последовательным соединением прямыми плечами. Показано, что при определенных условиях обе схемы могут обеспечить многократное понижение коммутируемой мощности и повышение мощности и стабильности выходных импульсов СВЧ-компрессора. Обоснована принципиальная возможность создания сверхразмерных каскадных СВЧ-переключателей. A microwave switch of a resonant compressor is an element that affects the operation process substantially. The switch must be able to disrupt the standing wave pattern of a cavity very fast but should not low the electric strength of the compressor that is has to withstand high values of electric field strength during cavity excitation time of several microseconds. So the limiting output power of a compressor is determined by the switch design and its operation. The switching element is usually located in the area of maximum electric field strength of a standing wave and the desire to put it in the area of lower field strength but keeping the same efficiency of operation is quite understood. Presumably the cascade switch might provide the required way of operation. The studied cascade switches were of two designs. The first one was formed by waveguide tees connected in series where the direct input arm of a next tee is connected to a side arm of a preceding tee. The electric field strength of the compressor of the first design was calculated relatively the power of an exciting microwave pulse. It was shown that the considerable decrease of the switched power value and the increase of the output power and stability of the output pulse parameters can be provided by both designs at definite conditions. The cascade switches may be designed on the basis of oversized waveguides as well. Режим доступа: по договору с организацией-держателем ресурса |
