The need for impedance matching is rooted in basic AC circuit analysis principles. In basic terms, maximum power transfer occurs when the current and voltage are in phase. This workshop examines the ins and outs of delivering the most power possible to an RF load. Q factor and its effect on matching network bandwidth are also described.
