A Complete Class of Harmonic Matching Networks: Synthesis and Application

This paper presents a class of distributed element matching networks that is able to guarantee the required impedance values at fundamental frequency and its second and third harmonics. The synthesis formulas of each considered matching network are defined and reported. By using these formulas, the synthesis capability of all proposed structures are then investigated and compared. Successively, a particular structure is selected, designed according to the proposed formulas, and realized; the performances obtained by simulation and measurements are shown.
