摘要：

Recent results obtained with microelectromechanical systems (MEMS) phase shifters demonstrate that their performance is much better than GaAs phase shifters using either standard or distributed designs. As such, the reliability of MEMS phase shifters is worse than of single switches since they employ 8-16 MEMS switches and do not tolerate failure in any of the switches. On the other hand, a large phased array will still function properly, albeit with a slightly decreased efficiency and higher sidelobes if 3-4% of the phase shifters fail.
