电压驻波比(VSWR)作为检测微波组件最重要的指标之一,是电路设计与制造水平的综合反映,其数值的高低决定了产品的质量。微波电路作为分布参数电路而言,信号的波长远远大于电路的微带线长。信号线上入射波与反射波相互作用形成了驻波。电压驻波比是传输线上最大电压与最小电压的比值,反映了在不同条件下反射回源端的信号能量。微波组件的VSWR主要受器件参数、器件间的级联匹配和装配工艺等因素影响。文中选取了微波组件装配工艺过程中影响电压驻波比的三大主要因素:接地效果、装配间隙、互连工艺,进行系列试验,通过理论分析和对试验结果的比较分析,我们得到实现较好电压驻波比性能所需的最佳微波组件的组装方法。
電壓駐波比(VSWR)作為檢測微波組件最重要的指標之一,是電路設計與製造水平的綜閤反映,其數值的高低決定瞭產品的質量。微波電路作為分佈參數電路而言,信號的波長遠遠大于電路的微帶線長。信號線上入射波與反射波相互作用形成瞭駐波。電壓駐波比是傳輸線上最大電壓與最小電壓的比值,反映瞭在不同條件下反射迴源耑的信號能量。微波組件的VSWR主要受器件參數、器件間的級聯匹配和裝配工藝等因素影響。文中選取瞭微波組件裝配工藝過程中影響電壓駐波比的三大主要因素:接地效果、裝配間隙、互連工藝,進行繫列試驗,通過理論分析和對試驗結果的比較分析,我們得到實現較好電壓駐波比性能所需的最佳微波組件的組裝方法。

As one of the most important indexes of microwave module inspecting, the voltage standing wave ratio (VSWR) comprehensively represents of the level of circuit design and fabrication, and the values of VSWR determine the quality of products. In the microwave circuit that is used as a parameter distribution circuit, the wavelength of signal is much longer than the length of microstrip line. The interaction of the incident and reflect wave in signal line results in forming the standing wave. As the ratio of maximum voltage and minimum voltage of transmission line, VSWR reflects the signal energy of reflecting to source end under different conditions. The VSWR of microwave module is mainly affected by the factors including module parameters, the cascade matching of devices, and assembly technology. In this paper, the three primary factors that affect VSWR during the microwave module assembling process, grounding effect, assembly gap, and interconnection technology, were chosen to conduct a series of experiments. By applying the theory analysis and comparing the experimental results, the optimum assembly method of microwave module to achieve a better VSWR was obtained.
