FIELD: radio engineering, communication.
SUBSTANCE: in the band amplifier containing the integrated amplifier, the first and second capacitors and the resistor, the first terminal connected to the common bus, and the second terminal with the input of the integrated amplifier whose output is the device output, an inductor connected to the first terminal to the input of the integrated amplifier, And the second terminal with the first terminals of the first and second capacitors. The second terminal of the first capacitor is the input of the device, and the second terminal of the second capacitor is connected to the output of the device.
EFFECT: increasing the dynamic range when amplifying signals in a narrow frequency range by reducing the noise level.
