摘要
射频通信电路设计思想与低频电路的不同,导致学生不能很好掌握其设计方法。将射频与低频电路的比较贯穿在教学环节,从"场"与"路"的分析比较,引入分布参数概念,强调电路中的分布参数对电路设计的影响。从网络参数的定义入手,强调散射参数的意义。从三极管的低频与射频等效电路的比较入手,引入放大电路稳定性的概念。从功率传输的角度引入电路匹配的思想,强调分布参数电路匹配设计的特点。在实践中取得了良好的效果。
There are the some differences between the design method of RF circuit and that of LF circuit,which causes the students can not to master it.Comparison method is introduced in teaching course to distinguish the concept of 'field' and 'road'.By comparing the RF circuit with that of LF,the influence of distributes parameter in the RF circuit design should be emphasized.Meanwhile,the meaning of S parameter is emphasizing by use of comparison of network parameter definition.Comparing the equivalent concept circ...
