Session 17 overview - RF cellular ICs

Abstract

At the current growth rate, the number of worldwide subscribers of cellular services is expected to exceed 1.5 billion by 2007. Today, cellular services for voice communications are primarily based on 2G systems, such as GSM and CDMA. However, with the rising demand for data services, the emerging 2.5G and 3G systems such as EDGE/GPRS and UMTS/CDMA2000, will play an increasingly important role in enabling multimedia services with feature-rich handsets. To support the enhanced functions in these handsets, RF cellular ICs must provide small-form-factor low-power solutions, while meeting stringent system-level compatibility requirements. A Fully Integrated Highly Linear Zero-IF CMOS Cellular CDMA Receiver 4:45 PM N. Kim, Qualcomm, San Diego, CA A 0.25µm highly linear zero-IF CMOS receiver with integrated LNA, down-converter, baseband filter, and VCO supports US and Japanese CDMA applications. The receiver IC occupies 5.8mm 2 and draws 56mA at 2.5V.
