| 摘 要： | 针对无线通信中多通道收发机前端功分器模块设计中面临的端口隔离度不高、插入损耗偏大的问题，提出了一种改进的威尔金森功分器设计方法.该方法基于威尔金森功分器原理，利用1/4信号波长传输线本身的长度增大功率分配端口的间距来满足系统中对于端口间距的要求，从而减小附加传输线带来的插入损耗，并采用HFSS电磁场仿真工具获取信号在传输线中的波长，由此设计了一款1分2和1分4威尔金森功分器.仿真结果表明该方法能够有效地提高功分器端口隔离度，并降低插入损耗.

| Abstract: | This paper proposes an improved Wilkinson power divider design scheme to solve the low port isolation and large insertion loss in the front-end power divider module of the multi-channel transceiver in wireless communication.Based on the principle of Wilkinson power divider, this design uses the 1/4 signal wavelength transmission line itself to increase the space between the power distribution ports, thereby reduces the insertion loss caused by additional transmission lines.And the HFSS electromagnetic field simulation tool is employed to obtain the wavelength of the signal in the transmission line.According to the proposed scheme, both 1 to 2 and 1 to 4 Wilkinson power dividers are designed.The simulation results show that this design can effectively reduce the insertion loss and improve the port isolation of the power divider. |
