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

Basic knowledge of power amplifier

Who should attend:

  • Engineering and lab managers
  • Research and principal engineers
  • RF and transceiver design engineers
  • Test engineers
  • Application and support engineers
