连续通道微带双工器仿真研究

摘要

In order to realize the miniaturization of diplexer, a continuous channel microstrip diplexer was designed by means of full wave simulation software IE3D. It was manufactured on the polytetrafluoroethylene substrate of 0. 254 mm. Its bands are 3. 8～4. 1GHz and 4. 1～4. 5 GHz, and insert loss is less than 2 dB, while its stop band loss is higher than 40 dB.%为了实现双工器小型化设计,采用全波仿真软件IE3D仿真设计了一种连续通道的微带双工器,所用是0.254 mm厚的聚四氟乙烯合成材料的基片,得到工作频段为3.7～4.1 GHz和4.1～4.5 GHz的双工器,获得了各通道带内插损小于2.2 dB,通带间带外抑制大于40 dB@中心频率的仿真结果,设计过程对信道化接收机系统的研究和设计具有重要意义.
