FREQUENCY MULTIPLIER

摘要

The invention can be used for telecommunications, measuring and other devices in order to produce stable superhigh frequency signals. An IMPATT diode 4 operating in the cascade break-down mode and having a sharp nonlinearity transforms an input signal in such a way that ultraharmonics which multiple in respect to the frequency of an input signal omega 0 occur in a frequency spectrum. An output stage of a multiplier is used in order to separate an output n omega 0 frequency and to suppress adjacent frequencies. In order to tune the output stage to the n omega 0 frequency, a tuning plug 8 and short-circuiting pistons 13 are used. The tuning plug 8 is arranged above an upper electrod of the IMPATT diode 4 (inside the axis of the diode). The tuning plugs 13 make it possible to tune resonance capacitance to the n omega 0 frequency and remove energy towards the output part of a T-bend in which a wave guide pass-band filter 15 is disposed. Said filter 15 is embodied in the form of sections of a waveguide 14 on whose E-plane a thin metallic diaphragm is arranged, said diaphragm being provided with windows 16 disposed along the axis of the waveguide. The inventive multiplier ensures high converting efficiency. <IMAGE>
