METHOD FOR GENERATION OF HIGH-FREQUENCY SIGNALS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2019 - IPC H03B5/06 

FIELD: radio engineering and communications.

SUBSTANCE: inventions relate to areas of radio communication and electronic warfare and can be used to design devices for generation of high-frequency signals at a given number of frequencies. Summary: method is based on conversion of constant voltage source energy to energy of high-frequency signal, interaction of high-frequency signal with direct transmission circuit made of three-terminal nonlinear element and four-terminal element, load and external feedback circuit. Four-terminal element is resistive. Load is made in form of the first two-terminal element with complex resistance. External feedback circuit used is a random four-terminal element connected to a three-terminal nonlinear element in a series-parallel circuit. Three-terminal nonlinear element and feedback circuit as single unit are cascaded between introduced second bipolar with complex resistance, simulating resistance of generator signal source in amplification mode, and input of resistive four-terminal element, to output of which load is connected. Excitation conditions in form of balance of amplitudes and balance of phases and matching condition are simultaneously performed at a given number of frequencies due to selection of frequency dependences of imaginary components of resistances of signal source in amplification mode x₀ and load x_l from the condition of providing generation excitation mode in form of an imaginary component equal to zero and equality of non-positive number of real component of denominator of transfer coefficient in amplification mode simultaneously at all specified frequencies of generated high-frequency signals at constant amplitude of constant voltage source in accordance with mathematical expressions.

EFFECT: increased number of generated oscillations frequencies, possibility to generate complex signals, reduced dimensions and weight of the device.
