Using ADS2019, How to set and measure tempature values for LNA?
I have designed LNA. I want to measure S21, S11, S22, S12 and NF for different values of Temperature Values such 36^{0}C, 70^{0}C, 15^{0}C. How to set different values of temperature for LNA using ADS2019. Can we set to all components (such as Resistors, Capacitors, Inductors, transistors, MLINs) to temperature separately( Right Click on the components and set temperature values to desired values).
Below I have attached designed LNA with set the temperature values independently on each component. Is this right way to set different temperature values on each component. Please clarify my doubts.

The most important component in your model  the transistor  is an S2P dataset at one fixed temperature. Your plan makes no sense if you only have that transistor data at that fixed temperature.

Yes, It is absolutely right. It does not make sense (s2p values will generate for particular temperature).
What should be done?, have we to take nonlinear model of transistor and set it different values of temperature and measure the Sparameters and Noise Figure of LNA.
Guide me, how to set different values of temperature to LNA and measure S parameters and NF of LNA.

Yes, nonlinear model sounds correct. And use a variable for temperatur, so that you can change it easily for all components.
For the ideal L and C elements in your design temperature will not have an effect.

I like the Modelithics libraries (license requires)
Some manufacturer also have good passive libraries, for example I often use Murata ADS libraries.
