Вступительная часть
В технике радиосвязи находят применение усилители со связанными
контурами. Каскад подобного усилителя содержит усилительный прибор
(транзистор или электронную лампу) и два, чаще всего одинаковых
колебательных контура между которыми существует индуктивная или
емкостная связь.
Приступим к исследованию АЧХ как функции частотной переменной
(обобщенной расстройки контура).

Выражения АЧХ для связанных контуров с индуктивной и емкостной связями
получились одинакового вида при соответствующих величинах, имеющих
смысл, перечислены в прошлой лекции. Поэтому анализ АЧХ проведем по
следующему выражению:

0300030000000000 рассчитаны одиночный колебательный контур и связанные
контуры при критической и сильной связи. Тогда их АЧХ будет иметь вид,
изображенный на рис. 3, причем максимальное значение каждой из
характеристик принято считать равным единице.
Для получения одной и той же заданной полосы пропускания добротности
контура должны быть различными: наибольшей будет добротность связанных
контуров с сильной связью, меньшее значение имеет добротность связанных
контуров при критической связи и наименьшее – добротность одиночного
контура.
Как видно, наилучшей избирательностью обладают связанные контуры при
параметре связи

НАСТРОЙКА И ПРИМЕНЕНИЕ СВЯЗАННЫХ КОНТУРОВ
Настройка системы связанных контуров заключается в подборе параметров
контуров, обеспечивающих на заданной частоте получения максимального
значения реакции на приложенное воздействие.
В случае внешнеемкостной связи задача сводится к получению максимального
напряжения на контуре. Поскольку активные проводимости контуров, как
правило, заданы и не подлежат изменению, процесс настройки сводится к
подбору оптимальных значений реактивных параметров контуров.
Представим упрощенную эквивалентную схему связанных контуров с емкостной
связью в виде (рис. 5).

f0010100030000000000 определяют следующие виды настройки (резонанса):
– простой резонанс;
– сложный резонанс;
– основной (индивидуальный) резонанс;
– полный резонанс.
Дадим качественную характеристику каждого из этих резонансов, имя в
виду, что настройка, как правило, ведется на критическую связь

00000) (при которой АЧХ максимально плоская).
а) Простой резонанс
Настройка осуществляется одним из контуров: либо 1, либо-2. При этом
имеет место 1-й частный резонанс, либо 2-й частный резонанс в
зависимости от используемого для настройки контура (рис. 6).
1-ый частотный резонанс 2-ой частотный резонанс
Рис. 6.
На практике настройка связанных контуров по методу получения простого
резонанса осуществляется в тех случаях, когда меняется частота источника
возбуждения. Например, настройка входных цепей приемников и выходных
цепей некоторых передатчиков малой и средней мощности. Критерий
настройки – наилучший эффект на выходе приемника или наибольший ток в
антенне радиостанции.
б) Сложный резонанс.
Настройка осуществляется одним из контуров и емкостью связи

Настройка на полный резонанс применяется в трактах, где частота
источника является неизменной, например в УПЧ.
При настройке должны быть приняты меры, чтобы ламповый вольтметр не
шунтировал контур.
Отметим, что рассмотренные виды настройки применимы и к другим видам
связанных контуров.
ЗАКЛЮЧИТЕЛЬНАЯ ЧАСТЬ
В лекции приведены АЧХ связанных контуров при сильной (А1) и критической
(А=1) связи, а также одиночного колебательного контура с одинаковыми ПП
и неравномерностью характеристик. Сопоставление этих характеристик
показывает, что за пределами ПП АЧХ связанных контуров убывают
значительно быстрее, чем у одиночного колебательного контура. Тем самым
обеспечивается более эффективное подавление тех гармонических
составляющих воздействия, частоты которых лежат вне заданной ПП. Это
объясняется тем, что связанные контуры, имея большее число элементов,
позволяют получить более совершенные характеристики. Следует также
отметить, что применение сильной связи позволяет получить большую
крутизну спада АЧХ за пределами полосы пропускания, чем в случае
критической связи при одинаковых неравномерностях в их полосах
пропускания.
