BROADBAND RADIO SYSTEM RECEIVING DEVICE Russian patent published in 2024 - IPC G06E3/00 

FIELD: physics.

SUBSTANCE: invention relates to analogue signal processing equipment and can be used in receivers of broadband communication systems, that is in communication systems with high redundancy of occupied frequency band, mainly in systems with high requirements for resistance to external interference (in particular, deliberate). Receiving device for a broadband radio system has a unit for recording an input signal, as well as an optical transparency with a recording of a detecting function and a summing photodetector in contact with it. Signal recording unit is a cylindrical coil of a light guide connected by one end to a signal source by means of an electro-optical converter and a displacement unit, and there is also a light guide for withdrawing optical signals from each turn of the coil of the light guide, which contacts the turns of the coil at points located along the generatrix of the cylinder, and also contacts the corresponding points of the transparency with the recording of the detecting function. Besides, there is also a second similar coil of light guide, in circuit of connection of input end of light guide of which with source of signal, in addition to unit of electro-optical conversion and unit of displacement, there is additionally included unit for conversion of input signal into mirror signal. At that, the second coil lead-out light guide is in contact with the transparency with the function record, which is the mirror one with respect to the above detection function, and the summing photodetectors in contact with said first and mirror transparencies are connected to the output of the device by means of a signal difference calculating unit.

EFFECT: creation of a receiving device for a broadband radio system, capable of operating in higher frequency ranges of radio waves, in decimetre and centimetre ones.
