design jfet lna

Hi all,
We all know the importance of noise figure in LNA design. One of the most frequently encountered thing is Zopt.
CAN ANYONE TELL HOW Zopt IS FOUND OUT PRACTICALLY ?
Thank you all :)

reference from datasheet or debug the Zopt to get the min Nf.
 

zopt of the transistor

ya buddy suppose you dont have datasheet or u r a device manufacturere itself .... then how are you gonna determine things like Rn, GAMMAopt over whole band.
