摘　　要：文中以公共端口的散射参数为优化目标,设计了一款S波段高温超导四工器。提出了一种通过匹配网络将4个平行耦合式发夹滤波器并联的四工器结构,该结构较好地解决了通道间的相互影响,减小了四工器尺寸;采用了主动式空间映射法,缩短了四工器设计周期。最终,4个信道的回波损耗都达到了-23 d B,证明了该文所提出方法的正确性和高效性。A S-band high temperature superconducting（ HTS） multiplexer was designed in the paper based on the scattering parameters. The multiplexer is comprised by four parallel coupled hairpin filter which are shunted through matching network. This scheme solves the interaction between channels and diminishes the overall size. The design cycle is shortened with active space mapping method. As simulating results,the return loss of multiplexer of all channels was less than-23 dB,which verify the validity and efficiency of the proposed method.
