An Introduction to Broadband Impedance Transformation for RF Power Amplifiers
By Anthony J. Bichler RF Micro Devices, Inc. his paper discusses broadband impedance-transforming techniques specific for radio frequency power amplifiers. Single and multiple Q matching techniques are demonstrated for broadband performance; here the reader will understand the importance of a load impedance trajectory relevant to load pull contours.

This tutorial article reviews impedance matching principles and techniques, as they are applied to power device matching in amplifier circuits
