Overview:
An increasing number of power amplifiers support envelope tracking technology to improve efficiency and therefore extend battery life in smartphones and tactical radios. This webinar explains the basic principles of envelope tracking and the test challenges involved in this technology. As envelope tracking is often used in combination with predistortion, this topic will also be covered. The requirements for a complete test solution are discussed and demonstrated using an efficient and compact test setup consisting of an advanced vector signal generator and signal analyzer from Rohde & Schwarz.

Attendees will learn:
  • Principles of envelope tracking technology and predistortion
  • Key challenges of testing envelope tracking power amplifiers
  • Efficient test setup for fast and simple power amplifier analysis

Prerequisites:
Basic knowledge of power amplifier testing

Who should attend:
  • Engineering and lab managers
  • Research and principal engineers
  • RF and transceiver design engineers
  • Test engineers
  • Application and support engineers

Presenters:

Johan Nilsson, Product Manager, Test and Measurement Division, Rohde & Schwarz, Munich
Johan Nilsson joined Rohde & Schwarz in Munich as a product manager for signal and spectrum analyzers in 2001. He is focusing on analyzer test solutions for mobile communications standards ranging from 2G and 3G to LTE and LTE-Advanced. Previously he worked at Ericsson as an RF system designer and as a delegate in the 3GPP standardization of UMTS. He graduated from Chalmers University of Technology in Sweden, and holds a master's degree in electrical engineering.



Matthias Weilhammer, Product Manager, Test and Measurement Division, Rohde & Schwarz, Munich
Matthias Weilhammer joined Rohde & Schwarz in Munich as a product manager in 2012. In this role he is responsible for the signal generator product portfolio. Previously, he spent five years working for Agilent as an application engineer with focus on mobile communications. Before that he worked for four years in R&D at Kathrein, where he was involved in hardware development for projects such as remote radio heads. Matthias graduated from the University of Applied Sciences in Munich, and holds a Diplom degree in electrical engineering and a master's degree in business administration and engineering.
