GaAs Technology Status and Perspectives for Multi-band and Multi-standard Challenges in Upcoming RF-Frontends

GaAs HBT technologies currently dominate the wireless handset PA marketplace due to their proven RF performance, time-to-market, and size advantages compared to other technologies. As with any technology, new customer specifications and requirements drive the development of next-generation devices and processes. Changing requirements regarding the bias circuit reference voltage (along with more sophisticated bias circuit functions) is a big challenge. Skyworks addresses this task by using GaAs BiFET technologies that allow low and no-reference circuits to be designed for just such applications.
