BANDPASS HIGH-SELECTIVITY LC-FILTER

摘要

FIELD: radio engineering.;SUBSTANCE: proposed filter comprises first and second inductor. First inductor first output is connected to input potential terminal of the device, while second inductor first output is connected to device output potential terminal. First outputs of first and second capacitors are connected to second outputs of first and second inductors. Second outputs of aforesaid capacitors are interconnected and connected to first terminal of third capacitor. Second output of the latter is connected to first output of third inductor. Second output of third inductor is connected to common bus. Additionally, proposed device comprises fourth, fifth and sixth capacitors. Note here that fourth capacitor connects device input and output potential terminals. Fifth capacitor is connected in between input potential terminal and common bus, while sixth capacitor is connected in between output potential terminal and common bus.;EFFECT: increased attenuation and improved match.;2 dwg
