Gregory explains the basics of Impedance Matching using the Smith Chart for RF Power Amplifiers and the usage of a Genetic Algorithm optimizer to fine tune the network, achieving the goals of Q factor, fundamental and harmonic termination. Impedance Matching over a broader range of harmonics is key for RF PA design. Different classes of operation requires different reactive terminations. The task of designing proper impedance matching networks, that also de-embed devices parasitics, quickly become unpractical using analytical tools or geometrical analysis over the Smith Chart.
