在ADS里导入了三极管的模型，但不知道输入输出阻抗？

怎么才能知道三极管的输入输出阻抗？

* - Please use the global SPICE parameter TEMP to set the junction 
*   temperature of this device in your circuit to get correct DC  
*   simulation results.  
* - TEMP is calculated by TEMP=TA+P*(RthJS+RthSA). The junction  
*   temperature TEMP is the sum of the ambient temperature TA and  
*   the temperature increment caused by the dissipated power  
*   P=VCE*IC (IC collector current, VCE collector-emitter voltage).  
* - RthJS is the thermal resistance between the junction and the  
*   soldering point. RthJS for this device is 290 K/W. RthSA is the  
*   thermal resistance of the PCB, from the soldering point to the  
*   ambient. For determination of RthSA please refer to Infineon's  
*   Application Note "Thermal Resistance Calculation" AN077. 
* - The model has been verified in the junction temperature range 
*   0癈 to +125癈. 
* - TNOM=25 癈 is the nominal ambient temperature. 
*   Please do not change this value.

做S参数仿真，S参数仿真面板里有个测试输入阻抗的原件Z-IN 插入仿真即可

网友回复:

非常感谢！

网友回复:

Z-in不是只能看输入阻抗么？

网友回复:

  下来看看 又得回复4次！
