- Abstract
- In this paper, a broadband 180" bit phase shifter using a new switched network was presented. A new network is composed of coupled lines (seetion) and 45" open and short stubs, which are shunted at the edge points of the main line, respectively. The design graphs provide the required G, Z, values, and 110 match and phase bandwidths. Four different 180" bit phase shifters, operated at 3 GHz, were designed and fabricated using the design graphs, and were experimented. The measured performances of each phase shifter were well in agreement with the corresponding the simulation ones over the operating bands, and showed broadband phase characteristics.
