Advances in High Power RF Design Webcast

WHY THIS WEBCAST IS IMPORTANT

High power RF design has long been considered "Black Magic"; an art rather than a science. Advances in key technologies and simulation tools have allowed engineers to disprove this myth and establish a new standard of expectations for the industry. It was not uncommon for an RF engineer to spend hours in the lab tuning an amplifier module with his kit of ATC capacitor sticks, foil tape, and an x-acto knife. Looking to compensate for parasitic elements and poor or non-existent device models, trial and error was the norm to get a working design. First pass success was only an elusive dream. Hybrid active loadpull systems, 3DEM simulations and better device models are allowing RF engineers to move into the virtual world, evaluating circuit designs and advanced architectures in simulation before narrowing down on the one design to prototype.

This webcast will show an overview of these challenges and the solutions provided by utilizing the advancements in key technologies and simulation tools. To facilitate this point, we will demonstrate a high power device model in simulation and determine optimum harmonic impedances. The simulated characterization will be compared to actual device loadpull and a matching circuit will be designed using EM simulation. Finally, 3DEM tools will be discussed as enabling the next generation of high power designs where integration is key.

WHO SHOULD ATTEND

For high power RF design engineers who want to learn a more scientific approach to design using simulation tools and advancements in key technologies.
