摘要

This study proposes a class of differential phase shifters based on theSchiffman type-C and type-F networks with wide phase shift range. After thephase and bandwidth properties of these two distinct networks are numericallyanalyzed, two unique advantages of wide phase shift range and wide phaseshift bandwidth are revealed. Next, the optimal design parameters for differentphase shift values up to 405 are presented to allow for a quick design process.To verify the proposed approach, a 180 differential phase shifter is designed,fabricated and measured. Good performance is achieved with an impedanceratio of 1.959 and 3.7 phase deviation over a phase shift bandwidth of 61%.
