| Abstract: | Due to "beam-squinting" effects which drastically influence the performance of electronic system,the application of time-delay offers an enhanced broadband bandwidth with less "beam-squinting" effects.The design of the broadband GaAs PHEMT monolithic true-time delay was described. The basic concept and design procedures were also introduced.A GaAs MMIC TTD with small size and excellent microwave performances from 2 to 8 GHz band was successfully developed.Insertion loss is less than 23 dB,overall delay time... |
