将多个S参数进行级联,最快捷的方法是在Simulink中使用RF Blockset里面的S-Parameter这个模块进行级联了,当然在MATLAB中您也可以实现S参数的级联,以两个2端口网络为例: ckt1 = read(rfckt.amplifier,'default.s2p');%读入第一个S参数,并将其设置为电路1ckt2 = read(rfckt.passive,'passive.s2p');%读入第二个...

passivity(s)plots the passivity of S-parameter object,sover a range of frequencies specified ins.Frequencies. Passivity is measured by the two-norm of the frequency-dependent transfer function H(f). example [ns,violationindex] = passivity(s)plots the passivity and returns the data of the passiv...
打开Library Browser,搜索function,找到S-function。 Library Browser 双击打开S-function编辑。 S-function name:函数名,可以自定义 S-function parameter:参数,需要添加变量时可以加上 S-function modules:需要用其他语言时加上 S-Function 点击Edit进入代码界面,一般会打开一个空白的m文件,下面是,代码模板。主函数的...
