摘　　要：为解决由于射频同轴电缆组件电压驻波比大引起的放大器自激问题,对影响电缆组件电压驻波比的因素进行了分析。通过电缆组件电压驻波比的计算公式,阐述了电缆剥头尺寸和组件焊接方法在电缆组件装接过程中的重要性,提出了降低组件电压驻波比的方法。通过对电缆剥头尺寸、组件焊接和测试方法的改进,降低了驻波比。经实际测试和应用,组件满足使用要求,消除了自激现象。In order to solve the amplifier self-excitation problem caused by larger voltage standing wave ratio（VSWR） of RF coaxial cable subassembly,analyze the factors affect the cable subassembly VSWR.Discuss the importance of cable peeled terminal size and subassembly soldering method in cable subassembly assembly,further get the methods of reducing subassembly VSWR.After improving cable peeled terminal size,subassembly soldering method and test method,the VSWR is reduced.Through test and appliance in practice,the subassembly can meet the appliance requirement and its self-excitation is avoided.
