ADS放大器模型参数含义

S21 : Forward Transmission Coefficient, use x+j*y, polar(x,y), dbpolar(x,y) for complex value
增益，X是增益大小，y是相位

S11 : Forward Reflection Coefficient, use x+j*y, polar(x,y), dbpolar(x,y), vswrpolar(x,y) for complex value

S22 : Reverse Reflection Coefficient, use x+j*y, polar(x,y), dbpolar(x,y), vswrpolar(x,y) for complex value
反射系数

NF : Noise Figure in dB [NF mode used for NFmin=0]
噪声系数
NFmin : Minimum Noise Figure at Sopt in dB [(NFmin,Sopt,Rn) mode used for NFmin>0]
最小噪声系数
Sopt : Optimum Source Reflection for Minimum Noise Figure [(NFmin,Sopt,Rn) mode used for NFmin>0]
最优源反射系数
Rn : Equivalent Noise Resistance [(NFmin,Sopt,Rn) mode used for NFmin>0]
等效噪声阻抗
Z1 : Reference Impedance for Port 1 (must be a real number)
端口1阻抗
Z2 : Reference Impedance for Port 2 (must be a real number)
端口2阻抗
GainCompType : =LIST: use model gain-compression specifications, =FILE: use S2D file

GainCompFreq : Frequency at which Gain Compression is specified
增益压缩频率
ReferToInput : Power Levels refer to INPUT or OUTPUT
功率参考
SOI : Second Order Intercept in dBm
二阶交截点
TOI : Third Order Intercept in dBm
三阶交截点
Psat : Power Saturation Point in dBm
功率饱和点
GainCompSat : Gain Compression at PSat in dB
功率饱和点的增益压缩

GainCompPower : Power Level in dBm at Gain Compression Specified by GainComp
这个值是根据ReferToInput : Power Levels refer to INPUT or OUTPUT而变化的，如果选择的是输入，那么就是输入P1dB, 如果是output，就是输出P1dB。
增益压缩功率

GainComp : Gain Compression in dB at GainCompPower
增益压缩

OutIM3_dBm:
3rd-order IM product power level at component
Output
