PRECISION SPECTRUM LIMITER Russian patent published in 2014 - IPC H03H11/00 

FIELD: radio engineering, communication.

SUBSTANCE: invention relates to radio engineering and communication. The precision spectrum limiter has an input voltage source, a first frequency-setting resistor, a first buffer stage, a second buffer stage, a first balancing capacitor, a second frequency-setting resistor, a common power supply bus, a second balancing capacitor, a third frequency-setting resistor, a fourth frequency-setting resistor, a first operational amplifier, having a voltage-to-current converter, a second voltage-to-current converter, a second operational amplifier, having a third voltage-to-current converter and a fourth voltage-to-current converter.

EFFECT: reduced effect of frequency of the single amplifier used in active elements on frequency response unevenness of a spectrum limiter in the pass band.
