NI AWR application Note explores Wideband PA design
NI (formerly AWR) has announced a new application note titled "˜Using NI AWR Design Environment Load-Pull Simulation for the Designer of Wideband High-Efficiency PAs'.
The note explores the design of power amplifiers using load-pull technology within NI AWR Design Environment software, specifically that of Microwave Office.
Using a Cree CGH40010F GaN HEMT in a Class F PA at 2000MHz as the example circuit, the application note details how power-added efficiency is maximised by optimising 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, says the company. The note is online at awrcorp.com/solutions/technical-papers.
