METHOD FOR CONSTRUCTING WIDE-CODE FREQUENCY CONVERTER OF RADIO SIGNALS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2017 - IPC H03D7/00 

FIELD: measuring equipment.

SUBSTANCE: method uses an electronic signal mixer and an electronic heterodyne oscillator of a fixed frequency, whose frequency stability is ensured by multiplying the frequency of a highly stable reference signal from the base device remotely from the base device by a substantially low frequency, constructed using a radio-photon approach with transferring the operations of forming and processing radio signals into the optical range. Moreover, the operation of electro-optical conversion is carried out by means of a first one-way optical modulator with a suppressed carrier, which separates the upper or lower sideband of the modulated optical signal. The operation of forming the tunable heterodyne signal is performed by means of a local optical latency signal generator using a highly stable semiconductor laser emitter and a recirculation loop comprising a frequency shift device based on a second one-way modulator with a suppressed carrier, respectively, releasing the lower or upper sideband of the modulated laser radiation, Optical signals and optoelectronic conversion performed by an ultra-wideband photodetector.

EFFECT: simplification of the step-up and down-converter of the frequency due to the formation of a discrete frequency tunable heterodyne signal based on an optical lattice signal generator.
