基于微带耦合线的四端口网络模型,提出了一种双耦合线巴伦,根据最小反射系数准则,推导出巴伦应满足的阻抗方程,并给出不同带宽所要求的耦合线奇偶模阻抗。最后给出ADS仿真结果及实验结果。

According to four-port network model of microstrip coupled-line,a double-coupled-line Balun is presented in this paper,then impedance equation is derived based on the lowest reflection coefficient criterion,odd(even) mode impedance of which Balun has different bandwidth are given.Last,ADS simulation result and experiment result are given.
