Next-generation wireless technology is rapidly generating economic growth by improving the way people live and work. Similarly, the development of fifth generation (5G) communication standards offers significant opportunities for Canada. Skyworks Solutions is partnering with a third party foundry to explore the capability of their enhancement mode GaN technology for implementation in next generation 5G products at millimeter wave frequencies. One key area of research will be transmitters capable of handling high-order modulated data at very high frequencies and key to their successful implementation will be new design techniques for power amplifiers. The goal of this research will be to leverage this unique technology which is capable of both operating at very high frequencies while simultaneously operating from a high supply voltage to create high power, highly efficient power amplifiers for use in the mmwave 5G frequency bands. This research will explore novel Doherty power amplifiers as a way to enable higher data rates, greater range, and longer battery life in new 5G devices at lower cost. This proposed two-year project will endeavor to characterize the process, and explore novel circuit techniques designed to fully exploit the potential of this unique technology.
