The purpose of impedance matching is to connect an arbitrary complex-valued load impedance to a source with a given resistive internal impedance (usually 50Ω) without causing input reflection and to ensure maximum power transfer from the source to the load. Impedance matching is one of the most important aspects of RF circuit design. The goal is to match inductive or capacitive loads to a 50Ω line or source. In this tutorial you will learn impedance matching using tuning stubs of different types and forms.
