Abstract
Large aperture phased array antennas operating at millimeter wave frequencies are designed for space-based communications and imaging platforms. Array elements are comprised of active T/R modules which are linked to the central processing unit through high-speed fiberoptic networks. The system architecture satisfying system requirements at millimeter wave frerquency is T/R level data mixing where data and frequency reference signals are distributed independently before mixing at the T/R modules. This paper demonstrates design procedures of a low loss high-speed fiberoptic link used for transmission of data signals over 600-900MHz bandwidth inside satellite. The FO link is characterized for transmission of analog and digital data. A dynamic range of 79dB/MHz was measured for analog data over the bandwidth. On the other hand, for bursted SMSK satellite traffic at 220Mbps rates BER of 2x10-7 was measured for Eb/No of 14.3dB.
