Title: Fundamentals of Envelope Tracking and Test

Date & Time: September 24, 2013; 8 AM PT/ 11 AM ET/ 3 PM UTC

Sponsored by: National Instruments

Presented by: Haydn Nelson, Product Manager, RF & Wireless

Abstract:
Despite advancements in cell phone battery technology, new demands such as more internal radios and larger and higher resolution screens place greater stress on battery life than ever before. As new technology is added to cell phones, engineers must consistently innovate to reduce power consumption. Envelope tracking is an increasingly popular technique used today to optimize the power-added efficiency of the RF power amplifier (PA). In this webinar, learn the fundamentals of envelope tracking using data gathered from an RF PA to identify crucial envelope tracking parameters. Based on these parameters, the webinar uses a PXI-based measurement system to demonstrate real measured signals that meet the stringent requirements of envelope tracking test.

Who should view this webcast?
This webcast features practical advice and examples for engineers who want to learn more about envelope tracking principles and design or test techniques. Familiarity with the fundamental elements of test is assumed but no PA design experience is required.
