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-shift keyed, amplitude-shift keyed, as well as amplitude-phase-shift keyed 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 network, two-pole controlled element connected to source of low-frequency control signal. Four-terminal network is made from the number of two-pole network, 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. Two-pole controlled element is connected to the longitudinal circuit between the output of the four-terminal network and the load with complex resistance. Source of a signal with complex resistance is connected to the input of the four-terminal network. Four-terminal network is selected as a complex one. 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 for modulation of amplitude and phase of high-frequency signals and its implementation device are proposed.
