Abstract
1. Способ генерации и частотной модуляции высокочастотных сигналов, основанный на преобразовании энергии источника постоянного напряжения в энергию высокочастотного сигнала, взаимодействии высокочастотного сигнала с цепью прямой передачи, выполненной из трехполюсного нелинейного элемента и четырехполюсника, нагрузкой и цепью внешней обратной связи, выполнении условий возбуждения в виде баланса амплитуд и баланса фаз, определяющих соответственно амплитуду и частоту генерируемых высокочастотных сигналов, условий согласования цепи прямой передачи с нагрузкой и условий согласования нагрузки с управляющим электродом трехполюсного нелинейного элемента, изменении частоты генерируемых колебаний по закону изменения амплитуды низкочастотного управляющего сигнала путем соответствующего изменения баланса фаз, отличающийся тем, что четырехполюсник выполняют резистивным, нагрузку выполняют в виде первого двухполюсника с комплексным сопротивлением, в качестве цепи внешней обратной связи используют произвольный четырехполюсник, подключенный к трехполюсному нелинейному элементу по параллельно-последовательной схеме, трехполюсный нелинейный элемент и цепь обратной связи как единый узел каскадно включают между введенным вторым двухполюсником с комплексным сопротивлением, имитирующим сопротивление источника сигнала генератора в режиме усиления, и входом резистивного четырехполюсника, к выходу которого подключают нагрузку, условия возбуждения в виде баланса амплитуд и баланса фаз и условия согласования выполняют при квазилинейной зависимости частоты генерации от амплитуды управляющего сигнала з1. The method of generation and frequency modulation of high-frequency signals, based on the conversion of the energy of a constant voltage source into the energy of a high-frequency signal, the interaction of a high-frequency signal with a direct transmission circuit made of a three-pole nonlinear element and a four-terminal, load and external feedback circuit, the fulfillment of the excitation conditions in the form amplitude balance and phase balance, respectively determining the amplitude and frequency of the generated high-frequency signals, matching conditions of the circuit direct transmission with the load and conditions for matching the load with the control electrode of a three-pole nonlinear element, changing the frequency of the generated oscillations according to the law of changing the amplitude of the low-frequency control signal by correspondingly changing the phase balance, characterized in that the four-terminal is resistive, the load is made in the form of the first two-terminal with complex resistance, as an external feedback circuit, use an arbitrary four-terminal connected to a three-pole nonlinearly the first element in a parallel-serial circuit, a three-pole non-linear element and a feedback circuit as a single node cascade between the input of the second two-terminal with complex resistance, simulating the resistance of the generator signal source in the amplification mode, and the input of the resistive four-terminal, to the output of which the load is connected, the excitation conditions in the form of a balance of amplitudes and phase balance and matching conditions, a quasilinear dependence of the generation frequency on the amplitude of the control signal
