FIBER-OPTIC PHOTOELECTRONIC ULTRAHIGH FREQUENCY MODULE Russian patent published in 2018 - IPC H04B10/25 G02B6/42 

FIELD: radio equipment; electronics.

SUBSTANCE: invention relates to the field of radio engineering, in particular to radiophotonics, and can be used in the design of antenna excitation systems and antenna arrays for communication, radar and electronic warfare. Fiber optic photoelectric ultra-high frequency module includes a symmetric fiber optic splitter, in the primary optical fiber of which powerful laser pulses of duration less than 2 ns are introduced in the spectral range of 820–860 nm, each of the secondary optical fibers is optically coupled to the AlGaAs-GaAs photodetector operating in the gate mode, photodetectors are electrically connected in series to the module, the number of photodetectors in the module being directly proportional to the magnitude of the effective wave resistance of the electrical load.

EFFECT: invention provides an increase in the power and speed of a fiber-optic photoelectric converter of high-power ultra-high frequency pulses of laser radiation.
