RECEIVING-TRANSMITTING OPTOELECTRONIC MODULE OF AN ANTENNA WITH A PHASED ANTENNA ARRAY Russian patent published in 2007 - IPC G01S13/66 

FIELD: the invention refers to antennas.

SUBSTANCE: the technical result is decreasing of heat generation of an optoelectronic receiving-transmitting module of an antenna with a phased antenna array near by the radiator, of mass and dimensions, galvanic isolation and energy independence of the array, increasing of the broadbandness, power, constructive flexibility, stability to electric disturbances. The input of the optoelectronic receiving-transmitting module of the antenna with a phased antenna array, consisting of an apparatus and an antenna parts is connected up to the first contact of the first switch, its second contact is in-series connected up with the first optical modulator to which the first laser is switched, an optical line of delay controlled by a line of photodiodes, an amplifier controlled by an attenuator, the first contact of the second switch whose second contact is connected up with the second optical modulator to which the second laser with a scheme of a feeding control and the first photo detector are switched, and the third - with the output. The output of the first photo detector is connected up with the first contact of the third switch, whose second contact is connected up with the antenna radiator, and the third - with the third optical modulator to which the third laser with the scheme of controlling the feeding is switched and the second photo detector connected with the input of the low-noise amplifier whose output is connected with the third contact of the first switch. The controlling inputs of the controlled line of the photodiodes, of the controlled attenuator, switches and the schemes of controlling of the feeding are connected with corresponding outputs of the controlling module.

EFFECT: decreases heat generation of the optoelectronic receiving-transmitting module of the antenna with phased antenna array.
