Abstract
Изобретение относитс к радиотехнике. Цель изобретени - повышение крутизны амплитудно-частотной характеристики (АЧХ) и уменьшение габаритов. Полосно-пропускающий фильтр содержит корпус 1, выполненный в виде отрезка запредельного круглого волновода, стержневые резонаторы (СР) 2 и крайние СР 3 и 4, установленные в корпусе 1 вдоль его продольной оси по радиусам под углом один относительно другого, винты 5 регулировки св зи, каждый из которых лежит в одной поперечной плоскости с соответствующим СР 2 и перпендикул рно ему по радиусу, входную и выходную линии передачи 6 и 7, св занные с СР 3 и 4. Дл настройки СР 2, 3 и 4 на резонансную частоту служат установленные соосно с ними винты 8. Кроме основных св зей в запредельном круглом волноводе возникает дополнительна св зь между СР 3 и 4. Наличие этой св зи обеспечивает повышение крутизны АЧХ, а поворот СР 2 позвол ет сблизить СР 3 и 4, что уменьшает габариты фильтра. 1 ил.The invention relates to radio engineering. The purpose of the invention is to increase the steepness of the amplitude-frequency characteristic (AFC) and reduce the size. The band-pass filter includes a housing 1, made in the form of a segment of an exorbitant circular waveguide, rod resonators (CP) 2 and extreme CPs 3 and 4, installed in the housing 1 along its longitudinal axis along radii at an angle relative to each other, screws 5 , each of which lies in the same transverse plane with the corresponding CP 2 and perpendicular to it along the radius, the input and output transmission lines 6 and 7, associated with CP 3 and 4. The set CPs for setting the CPs 2, 3 and 4 to the resonant frequency 8. screws coaxial with them In the outer circular waveguide, an additional connection arises between CP 3 and 4. The presence of this connection increases the steepness of the frequency response, and the rotation of CP 2 allows CP 3 and 4 to be brought closer together, which reduces the size of the filter. 1 il.
