    Abstract

    This paper describes a direct-conversion RF front-end designed for dual-band WiMedia UWB receiver. The front-end operates in band groups BG1 and BG3. It includes multi-stage LNAs, down-conversion mixers, a polyphase filter for quadrature local oscillator (LO) signal generation, and LO buffers. As targeted for mobile handset, several issues related to hostile environment are taken into account in this design. The front-end achieves approximately 26-dB gain and 4.9 to 5.6-dB noise figure (NF) across three subbands of BG1. In BG3 mode it obtains 23 - 26-dB gain and 6.9 to 7.7-dB NF. The front-end consumes 48.1 mA and 42.7 mA from a 1.2-V supply voltage in BG1 and BG3 operation modes, respectively. The chip was implemented in a 0.13-μm CMOS.
