First, you have to choose the class of your PA such as A, AB, B, C, F, G, H, HG... which implies different choices... say we choose class A that means that you have to bias your transistor in the middle of the V-I characterics... for your frequency range 2GHz I would not use distributed constants but concentrated (capacitors, inductors...)
In PA you generally match the input and tune the s22 to have highest PAE (this is a quantity to look at...) send me the configuration you wanted to used i''l give a look at it... bye
