下一代无线技术通过改善人们的生活和工作方式，正在迅速推动经济增长。同样，第五代(5G)通信标准的发展为加拿大提供了重大机遇。Skyworks Solutions正在与第三方代工厂合作，探索其增强模式GaN技术在下一代5G产品毫米波频率上的实施能力。一个关键的研究领域将是能够以非常高的频率处理高阶调制数据的发射机，而成功实施它们的关键将是功率放大器的新设计技术。这项研究的目标将是利用这一独特的技术，该技术能够在很高的频率下运行，同时在高电源电压下运行，以创建用于毫米波5G频段的高功率、高效功率放大器。这项研究将探索新型Doherty功率放大器，作为一种在新的5G设备中以更低的成本实现更高的数据速率、更大的范围和更长的电池寿命的方式。这个拟议的为期两年的项目将努力描述这一过程，并探索旨在充分开发这一独特技术潜力的新电路技术。

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.
