Abstract
Способ настройки многозвенных полосовых фильтров, заключающийся в настройке резонаторов фильтра, регулировке связей между резонаторами и связей крайних резонаторов с генератором и нагрузкой в соответствии с расчетными значениями, измерении частотной характеристики, обладающей большей крутизной, измерении частотной зависимости модуля коэффициента отражения, отличающийся тем, что настройку резонаторов (кроме центрального) и регулировку связей в соответствии с расчетными или экспериментальными значениями выполняют по характерным точкам на частотной зависимости коэффициента передачи при частичных включениях фильтра в измерительный тракт прибора, настройку центрального резонатора выполняют по частотной зависимости модуля коэффициента отражения при полном включении фильтра, а при настройке двух и более фильтров с одинаковыми параметрами первый настроенный фильтр используют как фильтр-образец, у которого измеряют параметры указанных выше характерных точек с последующим переносом измеренных параметров на настраиваемые фильтры.The method of tuning multilink bandpass filters, which consists in tuning the filter resonators, adjusting the connections between the resonators and the connections of the extreme resonators with the generator and the load in accordance with the calculated values, measuring the frequency response with greater steepness, measuring the frequency dependence of the reflection coefficient module, characterized in that the setting resonators (except the central one) and the adjustment of the bonds in accordance with the calculated or experimental values is performed by characteristic to the frequency dependence of the transmission coefficient for partial inclusion of the filter in the measuring path of the device, the central resonator is tuned according to the frequency dependence of the reflection coefficient module when the filter is fully turned on, and when setting two or more filters with the same parameters, the first tuned filter is used as a filter sample, which measures the parameters of the above characteristic points with the subsequent transfer of the measured parameters to custom filters.
