Linearity Aspects of High Power Amplification in GaN Transistors

Linearity (and its absence) is a major design constraint in practical high-frequency communication circuits, impacting both transmitter and receiver circuits. This chapter will introduce the general features of non-linearity and how it impacts circuit design, then dive into the origins of non-linearity in GaN devices specifically, detailing how it is modelled in the literature, and conclude with a discussion of designs at both the device level and circuit level which can help linearize systems based on GaN PAs.
