Advances in High Power RF Design

High power RF design has long been considered "black magic," an art rather than a science. It was common for an RF engineer to spend hours in the lab tuning an amplifier module with a kit of ATC capacitor sticks, foil tape and an X-ACTO knife. Compensating for parasitic elements and poor or nonexistent device models, trial and error was the norm. First-pass success was only an elusive dream. Advances in technologies and simulation tools have enabled engineers to disprove this myth and establish a new expectation for the industry. Hybrid active load-pull systems, 3D EM simulations and better device models enable RF engineers to move into the virtual world, evaluating circuit designs and advanced architectures in simulation before narrowing to one design to prototype.

This webcast will cover the challenges and the solutions provided by advancements in technologies and simulation tools. We will demonstrate a high power device model in simulation and determine the optimum harmonic impedances, comparing them to actual device load-pull. A matching circuit will be designed using EM simulation, and 3D EM tools will be discussed as the next generation for high power designs where integration is key.
