  • Author: Cristi Damian

Since the initial launch of GaN based Solid State Power Amplifiers by Advantech Wireless in early 2010, a lot of uncertainties and unknown issues have been clarified. We know today that GaN is the foundation of all new Power Amplifier development and design, and that it offers unmatched performance, reliability, and efficiency.

The purpose of this white paper is to characterize, in particular, the linearity of Advantech Based GaN SSPAS, when operated either in single carrier mode, or in multi carrier mode. A comparison with TWTs is long overdue, and here included. It is our belief that today,GaN exceeds power levels that were never achieved with any technology, and opens a new range of applications and opportunities for the Satellite Communication market.
