The WiMedia Alliance has proposed an UWB OFDM system with data rates from 53.3 to 480Mbps operating in the 3.1 to 10.6GHz band [1]. These data rates are comparable to wired specifications, such as USB 2.0, enabling many applications developed for wired platforms to migrate to this wireless technology. However, many of these products require compact and low-cost hardware platforms. Therefore, highly integrated all-CMOS SoCs may offer competitive advantages for UWB applications when compared with other less integrated approaches. We present an integrated RF transceiver and digital PHY on a single CMOS chip that includes all the active circuitry required for operation in Band Group #1 (3.1 to 4.8GHz), and supports both fixed-frequency and frequency-hopping modes in 528MHz bands.
