A 4-bit optical-true time-delay for 10-GHz phased array antennas using optical MEMS switches and fiber-optic delay lines

In this paper, experimental results on a 4-bit TTD for 10-GHz linear PAA systems are reported, using the optical MEMS switches and fiber-optic delay-lines, This 4-bit TTD is capable of scanning a radiation beam to one of 16 different directions within 200 /spl mu/s.
