Matching Networks For maximum power transfer, we need to match the load impedance to the source. Accomplished by adding passive networks between load and source called matching networks The networks also: Minimize influence of noise Linearize the frequency response

Matching Networks Can derive values mathematically or use smith charts Goal of matching networks Meet specifications while keeping cost down (minimize components)

Generic Solution for Optimal Power Transfer 1. Find and plot the normalized source and load impedance. 2. In the Smith Chart, plot circles of constant resistance (r) and conductance (g) that pass through the source impedance 3. plot circles of constant resistance (r) and conductance (g) that pass through the complex conjugate of the load impedance. 4.
