Hello,
First of all, i want to know about the subcircuit you are using in the design. whether it is just S2P file? or it is an amplifier model provided by the vendor?
Form the datasheet, i can understand that, you no need to add extra transmission lines and tuning (internally matched to 50 ohm). you just need to follow the circuit provided in the datasheet (2nd page).
Coming to your schematic, you connected Vcc and RFout directly. In general, we should use decoupling capacitors for RF IN and RF OUT (1nF as shown in datasheet).
Just add add capacitors at input and output (as shown in datasheet) and simulate. you should get some positive gain.
Comment back with simulation results...
