Power Amplifier designers have relied on 2-tone nonlinear Harmonic Balance simulations to characterize nonlinear performance and estimate things like EVM and ACPR. This technique is insufficient for high PAPR modulation schemes used in today’s wireless standards such as 5GNR. Specification-compliant simulations using modulated signals are an alternative.  However, with the complex modulation schemes and bandwidth requirements of 5G signals, a single modulated signal simulation may require more than 1 million time points.  This makes it impractical for designers to validate or investigate performance while covering the entire design space such as varying bias, temperate, design parameters, signal payload configurations, etc.

 In this presentation we discuss the latest techniques for speeding up these modulated-signal simulations of power amplifiers and complete transmitter systems.  The techniques provide accurate results in a fraction of the time allowing designers to do more complete design exploration for better confidence and circuit design.  The proposed techniques work in both of the most commonly used CAD tools, Keysight ADS (mostly for GaAs & GaN) and Cadence Virtuoso (mostly for CMOS & SiGe).



Anurag Bhargava is Customer Success Manager at Keysight Technologies based at San Diego, CA. He has more than 22 years of RF Industry experience which includes 6+ years as Scientist at Space Applications Center, ISRO, India His design experience includes active/passive circuit & System design for Satellite payloads & Radar systems. He has16+ years’ experience in Application Engineering domain at Agilent/Keysight. He is author of ADS Circuit Design Cookbook (now ADS example book) and manages his YouTube channel outside work hours to help new & experienced engineers to pick up and sharpen their RF design skills.
