摘　　要：由于宽带滤波器实现困难,传统工程中使用高通加低通滤波器的设计方法,缺点是体积大,指标差。创新地在罗杰斯版上应用管状电路,精确控制谐振枝节间容值,成功实现一款超宽带滤波器;实物测试与仿真结果能够拟合,滤波器相对带宽超过67%。该滤波器具备带宽宽、矩形度高、插损小、体积小、易制作、免调试等优点,实物已在工程中使用。Due to the diffi culty of implementing ultra-wideband fi lters,traditional engineering applications use a design method of highpass plus low-pass fi lters.The disadvantages are large size and poor specifi cations.This article innovatively applied a tubular circuit on the Rogers Edition to accurately control the capacitance between resonant branches to successfully implement an ultra-wideband fi lter.The physical test and simulation results can be fi tted,and the relative bandwidth of the fi lter exceeds 67%.This fi lter has the advantages of wide bandwidth,high rectangularity,small insertion loss,small size,easy production,and no debugging,and it has been used in engineering.
