摘　　要：耳蜗式多路耦合器在现代通信系统中有着广泛的应用前景。为了进一步减小耳蜗式多路耦合器的尺寸,采用集总参数与分布参数相结合的半集总参数元件,针对电路中的低阻抗线进行了有效的小型化设计。设计了一款工作于200 MHz^1 000 MHz的恒相对带宽为18%的10通道耳蜗式多路耦合器。仿真和测试结果表明,这种小型化方法使耳蜗式多路耦合器的尺寸缩减为137 mm×116 mm。Cochlear-based channelizer has a wide range of applications in modern communication system. Using the quasi-lumped element, an effective miniaturization design is proposed for the low impedance line in circuit, which is aimed at reducing the size of cochlear-based channelizer further. A 10 channels cochlear-based channelizer with 18% constant fractional bandwidth is designed,which works at 200 MHz-1000 MHz. The simulation and test results indicate this miniaturization method makes the size of cochlear-based channelizer to be reduced to 137 mm×116 mm.
