摘要
本文介绍了一种60GHz频段的片上巴伦及应用其与匹配部分的功率放大器设计过程。首先介绍了阻抗匹配部分使用的片上巴伦结构,采用调节中间抽头位置的方法来补偿巴伦的不平衡,仿真结果表明其幅度不平衡度为0.06dB,相位不平衡度为1.3°,损耗为2.1dB。并讨论了将该结构应用于该频段下功率放大器匹配连接部分的方法,最后验证了巴伦仿真的准确度问题。
This paper introduces a on-chip balun for60GHz and power amplifier which used it for impedancematching,method of tuning the position of center-tap is proposed to compensate for the imbalance of the balun.The simulation results show the amplitude imbalance is0.06dB,phase imbalance is1.3°,insertion loss is2.1dB.How to use this balun structure into the matching part of power amplifier for this frequency is also discussed.Finally,the accuracy of balun simulation is verified.
