摘　　要：为满足毫米波可重构通信系统需要,文中设计了毫米波可重构威尔金森功分器.首先在S波段设计了基于PIN二极管的可重构功分器电路和原型;然后在此基础上把原理外推到K/Ka频段,通过参数提取方法重点研究PIN二极管寄生参数的影响及其最佳匹配方式;最后设计了K/Ka频段的可重构功分器原型,并进行了仿真和测试.实测结果表明,K/Ka频段可重构功分器在工作带宽内,双路导通模式下端口1到传输端口(端口2和端口3)的插入损耗小于4.92 dB,传输端口之间的隔离度大于15.8 dB;单路导通模式下插入损耗小于1.65 dB,端口1和隔离端口之间的隔离度大于22.4 dB,实测结果与仿真结果基本一致.使用场路联合仿真的方法基于PIN二极管设计可重构功分器,在K/Ka频段考虑寄生参数的影响,设计的可重构功分器模型准确、结构简单,适合可重构系统应用.To satisfy the requirements for millimeter-wave reconfigurable communication systems,we designed a millimeter-wave reconfigurable Wilkinson power divider.At first,we designed an S band reconfigurable Wilkinson power divider based on PIN diode,and then the design principle was used in K/Ka band.We studied the effects of the parasitic parameters of PIN diode and the best matching method with parameter extracting,and designed a K/Ka band reconfigurable power divider.We conducted simulation and measurement,and the measurement results show that in the working band,in two-way mode the insertion loss from port 1 to transmission ports(port 2 and port 3)is below 4.92 dB and the isolation between two transmission ports is above 15.8 dB;in one-way mode the insertion loss is below 1.65 dB and the isolation between port 1 and the isolation port is above 22.4 dB.The measurement and simulation results generally agree with each other.Considering the effects of the parasitic parameters of PIN diode,and using EM/circuit co-simulation,we designed a reconfigurable power divider based on PIN diode in K/Ka band with is accurate,simple and suitable for applications in reconfigurable systems.
