Abstract

Полосовой перестраиваемый LC-фильтр, состоящий из входного полосового фильтра, содержащего первую катушку индуктивности, первый вывод которой соединен с входной потенциальной клеммой фильтра, второй ее вывод подключен к первому конденсатору и второй катушке индуктивности, вторые выводы второй катушки индуктивности и первого конденсатора соединены с общей шиной, и выходного полосового фильтра, содержащего третью катушку индуктивности, первый вывод которой соединен с выходной потенциальной клеммой фильтра, а второй ее вывод подключен ко второму конденсатору и четвертой катушке индуктивности, вторые выводы второго конденсатора и четвертой катушки индуктивности соединены с общей шиной, отличающийся тем, что в устройство дополнительно введены первая сигнальная шина, подключенная ко второму выводу первой катушки индуктивности, и вторая сигнальная шина, подключенная ко второму выводу третьей катушки индуктивности, кроме того, в устройство введены N идентичных по структуре секций, каждая из которых содержит третий, четвертый и пятый конденсаторы, а также входной и выходной электронные ключи, при этом третий конденсатор первым выводом подключен к первому выводу четвертого конденсатора и одновременно к первому выводу входного электронного ключа, второй вывод которого соединен с первой сигнальной шиной, второй вывод четвертого конденсатора подключен к первому выводу пятого конденсатора и одновременно к первому выводу выходного электронного ключа, второй вывод которого соединен со второй сигнальной шиной, при этом вторые выводы третьего и пятого конденсаторов соединены с общей шиной. Tunable band-pass LC filter, consisting of an input band-pass filter containing a first inductor, the first output of which is connected to the input potential terminal of the filter, its second output is connected to the first capacitor and second inductor, the second conclusions of the second inductor and the first capacitor are connected to a common bus, and an output bandpass filter containing a third inductor, the first output of which is connected to the output potential terminal of the filter, and its second output is connected to about the second capacitor and the fourth inductor, the second terminals of the second capacitor and the fourth inductor are connected to a common bus, characterized in that the device additionally introduced the first signal bus connected to the second output of the first inductor, and the second signal bus connected to the second output of the third inductor, in addition, N sections identical in structure are introduced into the device, each of which contains a third, fourth and fifth capacitor, as well as input and output th electronic keys, while the third capacitor is connected by the first output to the first output of the fourth capacitor and simultaneously to the first output of the input electronic key, the second output of which is connected to the first signal bus, the second output of the fourth capacitor is connected to the first output of the fifth capacitor and simultaneously to the first output output an electronic key, the second terminal of which is connected to the second signal bus, while the second terminals of the third and fifth capacitors are connected to a common bus.
