Webcast: RF System Architecture – Techniques for Optimal Design

Date: January 12, 2012
Time: 10 AM PT/ 1 PM ET/ 5 PM UTC
Presented by: Agilent Technologies
Presenters: Rulon VanDyke and David Leiss

About the Webcast:

Techniques to design RF System Architecture optimally to avoid costly system hardware integration failures downstream will be presented. Learn how to simulate and troubleshoot RF system block diagrams to determine the root cause of spurious signals through any path and at any node in the system. Also understand how RF system frequency planning is also related to the system architecture so that you can identify potentially bad designs early and transform them into an optimum one. Learn how to verify your RF system architecture in the latest wireless communication and aerospace defense applications with realistic digitally modulated RF signals.

Webcast: Using Simulated and Measured Load Pull for Optimal Performance in RF Power Amplifier Design

Why this Webcast is important:
RF Power Amplifier Design is possibly the most challenging RF design task. In Part 1 of this multi-part RF Power Amplifier Design Webcast Series, we begin with a key technique for attaining optimal PA performance, Load Pull Analysis. Determining optimal loads is the first step in maximizing your RF power amplifier design’s performance. This webcast will introduce you to many techniques which could save you weeks of time, identify bad designs early and turn a good design into a great one.

Topics covered include:
• Choosing the best bias point for optimal performance
• Determining the best load and source impedances
• Fundamental as well as harmonic load pull analysis
• Examine sensitivity of your completed design to external source and load variations
• Designing for best performance at X-dB gain compression or a specific power delivered
• Power-added efficiency (PAE), distortion and delivered power tradeoffs
• Determining optimal loads across a band of frequencies

Presenter:
Andy Howard, Senior Applications Engineer, and creator of the ADS Power Amplifier and Load Pull DesignGuides will cover these and more in this 60 minute webcast. Attendees will be provided with a detailed application note and the latest pre-release version of the Load Pull DesignGuide used in this webcast
