Abstract :
In this paper, the fiber-optic system with all-optical gain for local-oscillator (LO) signal distribution in the frequency range from 2 to 20 GHz between 64 sub-arrays (channels) in active phased arrays via fiber-optic cables is presented. The channel noise and gain of the distribution system and relative phase drift between the channels are studied theoretically and experimentally.
