Hi,


first of all, the resistors R_s and R_L should be fixed (50-ohm for example). R₁ and R₂ should be chosen for whatever bias point you want (Class A, B, C...). L₁C₁ form a resonator with ω₀²=1/L₁C₁. Same goes for L₂C₂. You can determine L₃ using the smith chart, or approximately by finding the total input gate capacitance, and then resonating it with L₃. Lastly L₅C₄ transform R_L to a lower impedance. You first need to determine what impedance that is by the amount of power you need (call it R_LL). Remember that the maximum power the circuit can deliver is approximately V_DD²/2R_LL. You can then use the smith chart. If you don't like the smith chart, L₅ can be calculated by Q=R_L/ωL₅ and R_LL=ωL₅/Q (those are approximations). Also, ω₀²=1/L₅C₄.
That should get you started, but you probably need to fine tune. Also, any node which you want to determine whether it is resonating or not, simple inject 1A AC current into it and check the AC voltage. Remember to disable other AC sources first though...

Hi,


I suggest you try and tune it first, and if you can't get it to work, you can try posting the actual schematic that you designed, as well as some simulation results.
