Abstract

This paper describes an externally modulated fiber optic link designed to transmit signals from the face of a phased array antenna to a receiver/signal processor. The architecture used modulator pods and remotely located optical sources which were interconnected by fiber. The size of the modulator pod and its power dissipation were minimized, and operation over a range of environmental conditions was achieved. Perturbations in the operating characteristics of the link due to environmental stressing was minimized through careful design. The RF design considerations were dominated by issues related to beamsteering and null formation, and cancellation ratio data is presented for a pair of links showing a null depth in excess of 60 dB.
