Abstract :
Next-generation wireless communication will require improved transmitter technology for a variety of applications, from advanced handsets to improved base stations. The UCSD Center for Wireless Communications has embarked on an ambitious program to develop improved power amplifier devices, architectures, and circuits for next-generation wireless communications applications. This article summarizes some emerging power amplifier technologies for future communication systems, including new linearization approaches, power management techniques, and new semiconductor devices
