摘　　要：针对收发频率间隔较近的双工器的设计难点,利用模式匹配法结合优化算法设计了一种新型S频段波导双工器,实现了在收发频率间隔较近时双工器高隔离度、高功率、小型化的要求。仿真及测试结果表明,该双工器接收频率为2.2~2.3 GHz,发射频率为2.025~2.12 GHz,在工作频率内驻波小于1.35,隔离度大于85 dB,整体长度小于700 mm,满足工程使用需求,有较好的实用价值。In order to meet the requirement of short frequency interval,mode matching method is used to design a novel S-band waveguide diplexer.The diplexer with high isolation in T/R ports is small in size and meets the requirements of high power.The simulated and measured results show that the receiving band is 2.2~2.3 GHz and the transmitting band is 2.025~2.12 GHz,the voltage standing wave ratio(VSWR)in working bands is less than 1.35 and the isolation is greater than 85 dB.The diplexer with length less than 700 mm has good practical value.
