双频段Gysel功分器设计
|
摘要
伴随着无线通讯技术的飞速发展,传统的wilkinson功分器在带宽、小型化以及双频段等方面已不能满足一些系统的设计要求。通过理论计算分析双频段微带线理论和工作方式,以及Gysel的工作原理,在此基础上结合Gysel功分器以及双频段微带结构,设计出一种新型双频段Gysel功分器。该双频段Gysel功分器主要工作在1.8GHz和5.8GHz两个频段。ADS仿真结果表明,该Gysel功分器在上述两个频段内的插损均小于3.45dB,回波损耗小于-10dB,隔离度大于等于10dB,在中心频率为1.8GHz频段中,3dB带宽为120 MHz,而在高频段5.8GHz中心频段中,3dB带宽为100MHz。
With the rapid development of wireless communication technology,the traditional wilkinson power divider can not meet the design requirements of some systems in terms of bandwidth,miniaturization and dual frequency band applications.This paper,firstly,analyzs the theory and priniciple of dual-band microstrip line and then analyzes theoretically the principle of Gysel power divider.A new dual-band Gysel divider is designed based on Gysel splitter and dual-band microstrip structure.The dualband Gysel power divider operates primarily in the 1.8 GHz and 5.8 GHz center bands.The ADS simulation results show that the insertion loss of the Gysel power divider in the above two frequency bands is less than 3.45 dB,the return loss is less than-10 dB,the isolation is greater than or equal to 10 dB,and the 3 dB bandwidth is 120 MHz in the center frequency of 1.8 GHz and the high-band 5.8 GHz center band,the 3 dB bandwidth is 100 MHz.
