HIGHLY SELECTIVE SECOND-ORDER LC BANDPASS FILTER Russian patent published in 2013 - IPC H03H7/12

Abstract RU 2501156 C2

FIELD: radio engineering, communication.

SUBSTANCE: highly selective LC bandpass filter has two inductors and eight capacitors which are connected so as to form two links, the first link providing an attenuation terminal lower than the medium frequency and the second link providing an attenuation terminal higher than the medium frequency.

EFFECT: high selectivity of the filter by realising two attenuation terminals at end frequencies and improving squareness of the attenuation characteristics.
