Paper Abstract

A 5-bit true-time-delay lines device having a packing density of 2.5 lines/cm2 with a minimum delay step of 50 ps which can controls antenna array with 9 subarrays simultaneously is designed, fabricated and demonstrated in this paper. The power fluctuation among 32 delay lines is controlled to within +/- 10 percent. A bandwidth of 2.4 THz is experimentally confirmed. TO verify the bandwidth of the device, up to 50GHz optically heterodyned microwave signal is generated, sent through the device, and then detected at the output end.
