A single-chip 0.13 /spl mu/m CMOS UMTS W-CDMA multi-band transceiver

Abstract

A single-chip, fully-integrated 3G UMTS/W-CDMA transceiver covering all operating bands specified by the current UMTS FDD standard has been implemented in a standard 0.13 mum CMOS process for use in FDD mobile applications. The design includes two fractional-N synthesizers with fully-integrated VCOs, on-chip tuning and PLLs as well as the zero-IF receiver and direct-upconversion transmitter paths. The chip is mounted in an extremely small lead-less package with just 5-by-5 mm outline dimensions and a maximum height of 0.8 mm and fully complies with ARIB W-CDMA and UMTS standards
