Design Harmonic Trap

I would like to design Class F Power amplifier but I don't know how can I design harmonic trap.

Does anybody know the design of hamonic trap?

Thank you very much

The Class F harmonic trap is tuned on 3rd harmonic of the fundamental signal, so just calculate the LC circuit for this frequency.

Thank you for your answer. I know that the class-F should design harmonic trap at fundamental and 3rd harmonic at the output port but I don't know how to design hamonic tuned on 1st and 3rd harmonic.

Use this free software, go to Tools/Calculator and find the LC values for specific frequency.
