摘要
介绍了一种60GHz频段的测试用片上巴伦,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0.01dB,相位不平衡度为2°,损耗为1.1dB。并讨论了如何用二端口矢量网络分析仪来测试巴伦的小信号参数以及如何用巴伦来测试差分电路的差分S参数。
This paper introduces a on-chip balun used for 60GHz frequency band test, 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 is 0.01dB, phase imbalance is 2°, insertion loss is 1. ldB. How to measure the small signal S parameter of the balun using two port vector network analyzer and how to measure the differential S parameter of the differential circuit using the balun are also discussed.
