For LNA design, how to get the transistor size (BJT) for the Ropt?

 I have started using SpetreRF recently and would like to know how to determine the length of the emitter of a BJT in order to have an optimum noise resistance Ropt equal to the resistance of the source Rs, e.g. 50 ohms.

-How this can be achieved through the simulation of Gopt and Bopt

-How this can be achieved through a simulation of Gmin

I will  be interested to know about application notes that are available on the topic

 

Regards, Aba
