During impedance matching, a specific electronic load (RL) is made to match a generator output impedance (Rg) for maximum power transfer. The need arises in virtually all electronic circuits, especially in RF circuit design.

Back to Basics: Impedance Matching (Part 1)” discusses the use of a transformer as a basic way to match impedance. This article will introduce the L-network, which is a simple inductor-capacitor (LC) circuit that can be used to match a wide range of impedances in RF circuits.
