摘要
依据经典的巴伦理论,采用微带传输线设计了100MHz的射频传输线巴伦。首先进行理论分析及其仿真设计,然后设计制作PCB,最后利用E5071C进行实际测试。结果为,插入损耗3.26d B,另一端口插入损耗为2.86d B,两端口有一定的不平衡,主要是由于相关电容误差和加工精度引起。进一步优化电容和传输线可以进一步提高巴伦的性能。
According to classical theory on balun,100MHz RF micro-strip transmission line balun was designed.Firstly theory analysis and simulation design was performed,then printed circuit board(PCB)was designed and prepared,and finally the device was tested using E5071C network analyzer.The designed balun featuers an insert loss of3.26dB and2.86dB of the other port.Certain unbalance exists in the two ports resulting from capacitance error and machining precision.So the the performance of balun can be further improved by optimizing the capacitance.
