METHOD FOR MODULATION OF AMPLITUDE AND PHASE OF HIGH-FREQUENCY SIGNALS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC H03C5/00 

FIELD: radio engineering and communications.

SUBSTANCE: invention relates to radio communication and can be used to generate required time forms of phase-manipulated, amplitude-manipulated, as well as amplitude-phase-manipulated and amplitude-phase-modulated signals in a given frequency band. Essence: high-frequency harmonic signal is supplied to input of modulator, modulator is made of four-terminal device, controlled element connected to source of low-frequency control signal. Four-terminal network is made from the number of two-terminal devices, which are not less than two, the parameters of which are selected from the condition of providing the required amplitude-frequency and phase-frequency characteristics in two states of the controlled element, which are determined by two levels of the low-frequency control signal. Controlled element is made in the form of a three-terminal nonlinear element and parallel as to voltage of feedback and switches it between the signal source and the input of the four-terminal element. Load with a complex resistance is connected to the output of the four-terminal network. Resistance of the signal source is selected as complex and the four-terminal element is selected as complex. Dependences of the complex elements of the classical transmission matrix of the four-terminal network on the frequency are selected from the condition of providing the specified phase dependencies ϕ_1,2 and modules m_1,2 of transfer functions on the frequency in the first and second states.

EFFECT: method is proposed for modulation of amplitude and phase of high-frequency signals and its implementation device.
