摘要
为了研究不同的多工器结构模型,介绍了一种国外最新仿生学在射频领域的应用成果——耳蜗式多路耦合器,分析了此类耦合器的一般设计方法;并从军用通信频率225～400MHz的角度上进行了设计仿真,通道滤波器相对带宽为3.6%,带内插损小于2dB,仿真验证了此种方案的可行性,为该频段的大功率多工器的研制做了有益的探索。
In order to study different multiplexer structure model, the paper describes a cochlear-based channelizer which is an achievement bionics has reached in the field of radio frequency abroad and analyzes the general design method of such a coupler. The channelizer is designed and simulated in 225-400 MHz military communication frequency. The constant relative bandwidth is 3.6%, and in-band insertion loss is less than 2 dB. The simulation verifies the feasibility of the method, which makes some beneficial explorations for the development of high power multiplexer in the band.
