RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

NI (formerly AWR Corporation) announces a new application note titled “Using NI AWR Design Environment Load-Pull Simulation for the Designer of Wideband High-Efficiency PAs” that explores the design of power amplifiers (PAs) leveraging load-pull technology within NI AWR Design Environment™ software, specifically that of Microwave Office. Using a Cree CGH40010F gallium nitride high-electron mobility transistor in a Class F PA at 2000 MHz as the example circuit, the application note details how power-added efficiency is maximized by optimizing source and load pull at the fundamental frequency, plus second and third harmonics. Additionally, the ability of the load-pull technique to inspect transistor voltage and current waveforms helps users gain confidence in their high performance designs.
