FIELD: radio communication.
SUBSTANCE: in device for demodulation of amplitude-manipulated and amplitude-modulated (AM) signals as non-linear element dipole non-linear element is selected, which is connected between source of amplitude-modulated signals and quadripole into longitudinal circuit (serially), high frequency load is connected to the output of quadripole, and low-pass filter is connected to high-frequency load, quadripole is made of at least three resistive dipoles, values of parameters of which are selected based on condition of provision of preset values of demodulator transfer coefficients modules in two conditions of non-linear element, which are determined with two extreme values of levels of input AM signal.
EFFECT: provision of preset values of modules of coefficients of demodulator transfer.
