This paper presents a dual-mode RF receiver front-end consisting of a LNA, an active single-ended-to-differential converter and a downconversion mixer. It uses a high performance 0.25-mum 60-GHz fr SiGe:C BiCMOS7RF integration technology from STMicroelectronics. The proposed RF receiver front-end (RFFE) is targeted to GSM1800 (1805-1880MHz) and WCDMA-FDD (2110-2170MHz) systems. The main motivation of this work is to share as many elements as possible in both modes avoiding conventional parallel receiver chains, which is not a cost-efficient solution. The overall RFFE achievable gain is around 40dB in both modes. The overall front-end noise figure (Friis formula) is less than 1.3dB for GSM1800 and 1.6dB for WCDMA mode. These performances fulfill the systems requirements. The complete RFFE circuit consumes 18mW in both operation modes at 2.5V supply voltage.
