Could you please tell me the difference between large signal s-parameter and x-parameter?
thanks
 

S-parameters are Port parameters and they are linear.They don't have any information about nonlinearity about the device.
X-Parameters behavioural parameters and they are nonlinear and they have nonlinearity information about the device.
 

LARGE signal s-parameter is not have non linear information?

No,large signal s-parameters are always linear.The difference between small signal s-parameters is signal drive level only.They corralate port realations such as reflection,transmission,isolation.
