Abstract

Многоканальный частотно-разделительный селектор, содержащий многообмоточный трансформатор, состоящий из первичной обмотки, одной или нескольких вторичных индуктивно связанных между собой обмоток, а также группу полосовых фильтров, входы которых подключены к вторичным обмоткам трансформатора, выходы полосовых фильтров являются независимыми выходами селектора, отличающийся тем, что к первому выводу первичной обмотки трансформатора подключены первый и второй конденсаторы, второй вывод первого конденсатора и второй вывод первичной обмотки трансформатора соединены с общей шиной, второй вывод второго конденсатора соединен с входной потенциальной клеммой селектора и с первыми выводами третьего конденсатора и первой катушки индуктивности, вторые выводы которых соединены с общей шиной, к каждому из выводов вторичных обмоток трансформатора подключен полосовой фильтр, состоящий из четвертого конденсатора, ко второму выводу которого подключена вторая катушка индуктивности, второй вывод которой соединен с пятым конденсатором и третьей катушкой индуктивности, второй вывод которой соединен с шестым конденсатором, второй вывод которого соединен с седьмым конденсатором и четвертой катушкой индуктивности, при этом вторые выводы пятого и седьмого конденсаторов соединены с общей шиной, а второй вывод четвертой катушки индуктивности подключен к восьмому конденсатору, второй вывод которого является выходом данного фильтра и подключен к соответствующему потенциальному выходу селектора.A multi-channel frequency-separation selector comprising a multi-winding transformer consisting of a primary winding, one or more secondary inductively interconnected windings, as well as a group of bandpass filters, the inputs of which are connected to the secondary windings of the transformer, the outputs of the bandpass filters are independent outputs of the selector, characterized in that the first and second capacitors are connected to the first terminal of the primary winding of the transformer, the second terminal of the first capacitor and the second terminal of the primary the transformer coils are connected to a common bus, the second terminal of the second capacitor is connected to the input potential terminal of the selector and to the first terminals of the third capacitor and the first inductor, the second terminals of which are connected to the common bus, a bandpass filter consisting of the fourth is connected to each of the terminals of the secondary windings of the transformer capacitor, to the second terminal of which a second inductor is connected, the second terminal of which is connected to the fifth capacitor and the third inductor, the second pin One of which is connected to the sixth capacitor, the second terminal of which is connected to the seventh capacitor and the fourth inductor, while the second terminals of the fifth and seventh capacitors are connected to a common bus, and the second terminal of the fourth inductor is connected to the eighth capacitor, the second terminal of which is the output of this filter and connected to the corresponding potential output of the selector.
