Use of High Accuracy GaN Models for Rapid High Efficiency Power Amplifier Design Success

  • Date: ¬†Tuesday, March 13, 2018
  • Event Time: 8am PT / 11am ET

Webinar Overview

This webinar will focus on model-based PA design methods, utilizing Keysight Advanced Design System simulation software along with state-of- the-art non-linear GaN models available from Modelithics for a range of Qorvo high-performance GaN-on-SiC power transistors. A systematic design flow will be exemplified for the case of a 160W Class AB GaN reference design that achieved all goals with no tuning required. Applications of similar flows to other high-efficiency modes such as Class E/F, Class J and Doherty® amplifier configurations will also be discussed.
Why This Webinar Matters
This webinar illustrates the features and applications of state-of-the-art GaN models combined with advanced EDA simulation templates, and helps design engineers to better understand and use GaN-on-SiC for PA design using discrete die or packaged devices. Engineers will gain insight into power amplifier design simulation for meeting high-power/high-efficiency requirements.
