Description

В СЛОЖНЫХ узкополосных фильтрах дл  получени  стабильных частотных характеристик примен ют набор пьезоэлектрических резонаторов , каждый из которых настроен на одну частоту. Недостатком таких фильтров  вл етс  большой разброс температурных характеристик отдельных пьезоэлектрических резонаторов.COMPLEX narrowband filters use a set of piezoelectric resonators, each tuned to a single frequency, to obtain stable frequency characteristics. The disadvantage of such filters is the large variation in temperature characteristics of individual piezoelectric resonators.

Предлагаемый пьезоэлектрический резонатор изображен па фиг. 1 и 2. Он состоит из цельнокристаллического элемента 1 и электродов 2.The proposed piezoelectric resonator is depicted in fig. 1 and 2. It consists of an all-crystal element 1 and electrodes 2.

Цельнокристаллический элемент 1 состоит из нескольких частей, разделенных прорез ми, направленными вдоль длинной стороны резонатора . Отдельные части элемента имеют резонанс колебаний типа раст жение-сжатие на различных частотах. Прорези позвол ют ослабить взаимное вли ние отдельных частей резонатора и нроизводить их частотную настройку независимо друг от др)та. Отдельные элементы могут иметь одну общую пару электродов (фиг. 1) и отдельные пары электродов (фиг. 2). Отдельные части резонатора имеют идентичные температурные характеристики. Благодар  незначительному вли нию отдельных частей резонатора они могут быть включены в различные электрические цепи.The all-crystal element 1 consists of several parts separated by slots directed along the long side of the resonator. Separate parts of an element have a resonance of oscillations such as tension-compression at various frequencies. The slits make it possible to weaken the mutual influence of individual parts of the resonator and to produce their frequency setting independently of each other. Individual elements can have one common pair of electrodes (Fig. 1) and separate pairs of electrodes (Fig. 2). Separate parts of the resonator have identical temperature characteristics. Due to the insignificant influence of individual parts of the resonator, they can be included in various electrical circuits.

Предмет изобретени Subject invention

Пьезоэлектрический резонатор с цельнокристаллическим элементом со сплошными или разделенными электродами, отличающийс  тем, что, с целью уменьшени  взаимного вли ни  между отдельными его част ми, эти части отделены друг от друга нрорез ми, выполненными с одной или обеих сторон пьезокварцевой пластины резонатора.A piezoelectric resonator with an all-crystal element with solid or separated electrodes, characterized in that, in order to reduce the mutual influence between its individual parts, these parts are separated from each other by cutters made on one or both sides of the piezoquartz resonator plate.
