Applications for GaAs and silicon ICs in next generation wireless communication systems

Emerging applications for portable wireless voice and data communications systems are requiring increased data rates and functionality. Meeting cost and performance goals requires careful attention to system level design and partitioning such that appropriate technologies are employed in cost-effective solutions. New circuit designs and techniques are required to meet size, power, and regulatory restrictions. This provides an exciting opportunity for GaAs, silicon and other technologies. This paper will present several system level architectures for present and proposed radio-based communication systems. The paper will address requirements driving the technologies and appropriate applications of GaAs and silicon integrated circuit technologies.
