Semiconductor Series Research (10) RF Systems - Third Generation Semiconductor GaN RF Chips (C03: Gallium Nitride RF Systems and Devices)

This chapter introduces some technologies that design Gallium Nitride (GaN) for power amplifiers (PAs) and other applications, describing how GaN is widely used in RF (Radio Frequency) front ends. We also explore how technology leaders provide discrete, monolithic microwave integrated circuits (MMICs), and highly integrated modules to accommodate multiple application areas. Additionally, we explain the … Read more
