BAND-PASS LC-FILTER WITH REJECTION OF CONCENTRATED INTERFERENCE IN SERVICE FREQUENCY BAND

摘要

FIELD: radio engineering.;SUBSTANCE: band-pass LC-filter includes the first and the second low-pass filters, the first and the second group of inductance coils, high-pass filter, amplifier, electronic switches and discrete capacitors of variable capacity.;EFFECT: improving operating characteristics of the device, increasing the width of rejection band, increasing the attenuation level in stop band, enlarging the service frequency band and reducing KCB (standing-wave ratio).;1 dwg
