Power Amplifier Design
Power Amplifier Design Webinar Series
Latest technologies drive for more bandwidth and higher frequencies. Power Amplifier (PA) designers are challenged with high peak-to-average ratios, while maintaining high power added efficiency and linearity. In these webinars we address several aspects that are of importance when doing PA design, like Load Pull techniques, EVM and ACPR simulations, Electrothermal analysis and many more.

How to Setup and Run Load Pull Simulations: The Basics
How to Setup and Run Load Pull Simulations: The Basics

Load Pull is an important step in the design of Power Amplifiers. It helps you see what key specifications like output power, efficiency and gain could be attained from a device and determine the optimal load impedance. The presentation shows how to set up and run simple load pull simulations and examine the results.
Advanced Load Pull Simulation and Analysis Techniques
Advanced Load Pull Simulation and Analysis Techniques

Recent improvements have been made with respect to load pull simulation in PathWave Advanced Design System (ADS). This session will show methods of sweeping power up to an X-dB gain compression point (but not beyond), graphically selecting regions of the Smith chart, and analysing results for best Doherty performance. 
Performing EVM and ACPR Simulations
Performing EVM and ACPR Simulations

When designing power amplifiers for communication systems, it is important to meet the ACPR and EVM specifications while delivering a specified output power. This session shows various techniques for running these types of simulations in PathWave Advanced Design System (ADS) and the things you need to consider when performing such simulations.
Designing and Simulating Doherty Power Amplifiers
Designing and Simulating Doherty Power Amplifiers

Doherty power amplifier configurations have become a mainstay in the wireless infrastructure marketplace due to their efficiency enhancement capabilities when using various communication signals with high peak-to-average power ratios. This session will cover an example that was developed in cooperation with Freescale (now NXP) and which was used at a Doherty design workshop at IMS. We will demo an updated PathWave Advanced Design System (ADS) workspace from the workshop that goes through a Doherty design flow.
Simulating Digital Pre-Distortion
Simulating Digital Pre-Distortion

Power amplifiers with high Peak-to-Average Ratio (PAR) signals can create non-linearity problems. When a high power signal is applied to the PA input, the PA can't always linearly amplify the signal, resulting in a situation leading to gain saturation and distortion. Digital Pre-distortion (DPD) technology is widely used to compensate for the non-linear behaviour of power amplifiers. We will show in a PathWave Advanced Design System (ADS) example the latest digital pre-distortion simulation capabilities and techniques.
Integrated 3D EM/Circuit Co-Simulation Environment for First-Pass Design Win

Industry trends in RF and Microwave Design drive for more functionality in smaller form factors. Denser integration and integrated modules at high frequencies require circuit simulation to be combined with 3DEM simulation to account for inevitable parasitic and coupling. In this webinar, you will learn how to assemble and analyse multi-technology components and see how RFPro 3DEM-circuit co-simulation is iteratively used during design tweaks.
