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 quadripole and high frequency load into longitudinal circuit (serially), 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 that are determined by two extreme values of levels of input AM signal. ^ EFFECT: provision of preset values of demodulator transfer coefficients modules. ^ 5 cl, 6 dwg |
