FIELD: radio engineering. ^ SUBSTANCE: method is realised by insertion of a magazine of discrete capacitors into a strip discretely tuned LC-filter, and the magazine comprises N sections and three potential buses, the first of which is connected to the input potential terminal of the device, the second potential bus is connected to the output potential terminal of the device, the third potential bus is connected to the second output of the third capacitor. ^ EFFECT: improved coefficient of transfer and reduced irregularity of amplitude characteristic in the working band of frequencies in process of tuning. ^ 1 dwg |
