rf power transistor zout

How to calculate Zout of Power Transistor if S parameter of the transistor is given, and its need to match to 50 oham line, no other information is given ?

Thanks.

But you don't need the S22 to deliver the "power" from this transistor because S-parameters are small signal parameters and they can't be used in power applications.
Instead, optimum output impedance is used to calculate the power that will be deleivered by the power transistor
