  1. Model-Based GaN PA Design Basics: GaN Transistor S-Parameters, Linear Stability Analysis And Resistive Stabilization 9/19/2019

    S-parameter matching is used to maximize gain and gain flatness in simple linear RF/microwave amplifier designs. This same S-parameter data is used to develop matching networks that address amplifier stability. This paper discusses the importance of using modeling for basic S-parameter and stability analyses in the gallium nitride (GaN) power amplifier (PA) design process. It also focuses attention on a simple two-port stability analysis derived from linear S-parameter calculations. The nonlinear Qorvo GaN power transistor model from the Modelithics Qorvo GaN Library, in combination with simulation templates and Keysight Advanced Design System (ADS) software.
