FIELD: radio engineering, communication.
SUBSTANCE: rejection LC-filter comprises a low-pass filter which consists of N inductance coils connected in series to each other, wherein each of the leads of said inductance coils is connected to a capacitor and second leads of the capacitors are connected to a common bus. The first lead of the first inductance coil of the low-pass filter is connected to a first circuit consisting of parallel-connected inductance coil and capacitor; the second lead of the last inductance coil of the low-pass filter is connected to a second circuit consisting of parallel-connected inductance coil and capacitor; the second lead of the second circuit is connected to the output potential terminal of the filter.
EFFECT: improved frequency response unevenness and high transmission coefficient in the operating frequency band while providing the required rejection of one of given frequencies.
