【摘要】 介绍了一种仿生学在射频电路的全新应用——耳蜗式多路耦合器,提供了该类多路耦合器的设计原理,给出了详细的拓扑结构和设计方法。结合耳蜗式多路耦合器的特点,提出了一种有效的小型化方法。并在此方法的基础上设计了一款工作于200MHz-1000MHz恒相对带宽18%的10通道多路耦合器。仿真结果验证了该类多路耦合器的可行性,为以后的研究工作打下了良好的基础。更多还原

【Abstract】 The paper describes a new application of bionics in RF circuit—cochlear-based channelizer, provides the design principle about this type of multi-coupler, and gives a detailed topology and design methods. Combining the characteristic of cochlear-based channelizer, this paper presents an effective method of miniaturization. A 10 channels cochlear-based channelizer which works in 200MHz-1000 MHz with 18% constant fractional bandwidth is designed based on this method. Simulation results show the feasibility of this type of multi-coupler, which lays a good foundation for future research.更多还原
