| Abstract: | LVDS is a low swing, differential signaling technology which allows single channel data transmission at hundreds or thousands of Megabits per second (Mbps). In this paper, a scheme of a digital beam forming processor for phased array radar using LVDS is proposed. Two types of LVDS circuits using microstrip and twisted pair of lines are designed and implemented. Some high speed circuit design rules are successfully applied during printed-circuit board design stage. The performances of the designed circuits are measured and some useful results are achieved. |
