Mini tutorials · Impedance matching
Why match, what Z and Γ mean, how series and shunt move on the Smith chart — then the interactive matcher as the lab, plus a practical ESP32 2.4 GHz vignette.
Lessons
Max power when RL = RS. Bigger VL is not more power.
Series RL/RC · phasor plus |Z|(f) and phase.
Unit disk · 1 − |Γ|² is delivered power · RL · VSWR.
Const-R vs const-G strokes on a mini Smith chart.
Click a point → z, Z, Γ. Gold = this R, teal = this X.
