FIELD: radio engineering, communication.
SUBSTANCE: apparatus for generating high-frequency signals has a dc voltage source, a two-terminal nonlinear element with a negative differential resistance, a reactive four-terminal circuit, an additional two-terminal circuit; the reactive four-terminal circuit is in form of a "П"-shaped connection of three two-terminal circuits, the first and third of which are in form of two parallel-connected circuits of elements with parameters whose values are defined according to given mathematical expressions.
EFFECT: wider range of generated vibrations and generation of high-frequency signals at a given number of frequencies.
