摘　　要：利用低温共烧陶瓷(LTTC)工艺,成功研制一款以波长阶跃阻抗谐振器(SIR)满足对应性能指标的六阶带通滤波器。为了提高反馈性能并抑制干扰信号,于是采用四分之一波长的阶跃阻抗谐振器设计一款典型的六阶带通滤波器,并通过仿真与试样测试来验证带通滤波器的改进结构特性。理论与试样实验分析结果表明,该带通滤波器的抗干扰性能好,整体的制造工艺简单,且花费的成本偏低。该带通滤波器适合在市场内进行推广。By using the low temperature co-fired ceramic(LTTC)process,a six-order band-pass filter is designed to meet the corresponding performance index with wavelength step impedance resonator(SIR).In order to improve the feedback performance and suppress the interference signal,the filter uses a quarter-wavelength step impedance resonator to design a typical sixth-order band-pass filter,and through the simulation and sample test to verify the improved structure of the filter.The results show that the bandpass filter has good anti-jamming performance,simple manufacturing process and low cost.The Bandpass Filter is very suitable for market application.
