Description
Summary:TDMA based 2/2.5G digital systems like GSM/EDGE and CDMA (spread spectrum) based digital systems like IS95 for wireless cellular communications have created an increasing market within Europe, the US and SEA since 1992 and have gained nearly world-wide acceptance. The total number of cellular subscribers has already reached the range of 1 billion and may grow to 2 billion by end of this decade. The 3G WCDMA based UMTS system started service in Japan in 2001 and in Europe in 2003. Advanced smart cellular phones are, already today, extended with cordless, navigation, broadcasting, and other services, e.g. DECT, WDCT, BT, Zigbee, RKE, GPS/Galileo, FM radio, DAB, TV, DVB, WLAN, RF TAGs. These multi-system phones enable in the future nearly unlimited wireless connectivity and services. This paper gives an overview on the trends and challenges for radio front ends in cellular and non cellular systems-in semiconductor integration, which enables small, lightweight, powerful, low cost smart cellular phones.
