FIELD: radio electronics. SUBSTANCE: automatic level regulation device has amplifier 18, which has controlled gain, quadrature-demodulation stepping-down converter 20, which is connected to amplifier 18, and is used for translation of output signal frequency in modulation frequency. Two active low-pass filters 76 and 78 with high amplification gain provide suppression of out-of-band signal within band of modulation signals. Circuit for suppression of constant level penetrating signals suppresses penetrating signals, which cause constant level drift and are produced by stepping-down converter 20 and low-pass filters 76 and 78. In addition, automatic level regulation device generates received power signal on basis of output signal level. Saturating integrator 22 compares received signal power to reference signal and generates gain regulation signal by means of integration or abstaining from integration on basis of reference signal values, received signal power and amplification gain regulation signal. EFFECT: decreased information losses at carrier frequency. 9 cl, 13 dwg
