In this paper, a broadband 180/spl deg/ bit phase shifter using a new switched network was presented. A new network is composed of coupled lines (section) and 45/spl deg/ open and short stubs, which are shunted at the edge points of the main line, respectively. The design graphs provide the required Z/sub m/, Z/sub s/ values, and I/O match and phase bandwidths. Four different 180/spl deg/ bit phase shifters, operated at 3 GHz, were designed and fabricated using the design graphs, and were… CONTINUE READING
