| 摘 要： | 对微波BJT器件的级联噪声模型(En-In)以及噪声参数的提取进行了研究.从复相关理论出发,求得噪声参数Fmin,Rn和Γopt的表达式.根据二端口器件的本征H参数和噪声源配置,推出了En-In模型的表达式方程.将En-In代入噪声参数的表达式中即完成了对噪声参数的抽取.后给出器件AT41410和AT41411噪声参数抽取结果,并与实测值进行比较,结果表明提取值与测量值基本上一致.

| Abstract: | The cascade noise model (En-In) and the noise parameters extraction of microwave BJT device were studied.Using the complex correlation theory,the expressions of the noise parameters Fmin,Rn,Γopt were obtained.According to the intrinsic H-parameters and noise source configuration of the two-port device,the En-In model equations are determined.By substituting the En-In equations into the noise parameters expressions,the noise parameters are extracted.The experiments on the two devices AT41410 and AT41411 show that the results extracted are almost in accord with the values measured. |
