Cellular Handset Technology System Requirements and Integration Trends

Abstract

Summary form only given. Cellular handset technology system requirements and integration trends In ten years the cellular telephone has evolved from a tool for the professional to an indispensable consumer product with a very high market penetration. At the same time, the handset cost, weight, and standby time have been reduced by more than a factor often. These factors have been critical for the success story of the mobile phone. The technical aspects behind the rapid handset evolution are discussed. In particular, what advances in: the radio architecture, for example the zero-IF GSM receiver; the baseband (CMOS) technology; and the radio system design areas have meant for the reduction of size, weight, cost, and power consumption is discussed. Future challenges, like SW-DSP-digital-RF partitioning, linear multi-mode modulation with high linearity requirements, digital leakage issues, and power consumption limitations in multimedia handsets are discussed with future generation handsets in mind.
