Abstract
In the paper, different architectures of fiber-optic distribution systems of microwave signals for active phased array antennas are studied. The fiber-optic system with all-optical gain for microwave local oscillator signals distribution is presented. The fragment of proposed system is realized and characterized. It is experimentally shown that the developed distribution system provides noise-to-signal ratio of -150 dBc/Hz, output channel power about 1 mW and phase fluctuation between channels less than 1°.
