Abstract

Укв-лентовият филтър ще намери приложение в радиотелефонните уреди. Той се произвежда чрез опростена технология и е с подобрени качества по отношение на стабилност, необходимост и използване на пространство и регулиране. Укв-лентовият филтър е изграден от свързани помежду си и капацитивно настроени резонатори, които съдържат високочестотни бобини (вчб), закрепени към тела на бобините (тб), които са разположени върху обща основна плоча. Към плочата 2 е закрепен екраниращ корпус, чийто брой е равен на броя на резонаторите. Между сегментите на екраниращият корпус са оформени отвори за връзка между резонаторите, като към първия и последния резонатор са включени свързващи намотки. За филтъра е характерно, че вчб са разположени върху тб на разстояние от основната плоча и на еднаква височина една спрямо друга, при което горните им краища са свързани с проводници, поместени във вътрешността на тб, а долните им краища са свързани с плочата. Капацитивният настройващ елемент (кне) е разположен във вътрешността на тб на височина между равнината на плочата и равнината на най-долните навивки, като едната арматура на кне е свързана с проводника, а другата с настройващ заземен елемент, който е с възможност за изместване спрямо основната плоча. 9 претенции, 5 фигуриThe UV-band filter will find application in radiotelephone equipment. It is produced by simplified technology and has improved qualities in terms of stability, necessity and use of space and regulation. The uv bandpass filter is made up of interconnected and capacitively tuned resonators that contain high frequency coils (vcb) attached to coil bodies (tb) that are located on a common base plate. A shielding housing is attached to plate 2, the number of which is equal to the number of resonators. Openings are formed between the segments of the shielding housing for connection between the resonators, and connecting coils are connected to the first and last resonators. It is characteristic of the filter that the VCBs are located on the tb at a distance from the main plate and at the same height relative to each other, where their upper ends are connected to wires placed inside the tb, and their lower ends are connected to the plate. The capacitive tuning element (kne) is located inside the tb at a height between the plane of the plate and the plane of the lowermost windings, one armature of the kne being connected to the wire and the other to a tuning ground element that is capable of displacement relative to the base plate. 9 claims, 5 figures
