摘要

提出了一种0.44mm/sup 2/全集成的3波段MB-OFDM超宽带合成器，采用0.25/spl mu/m SiGe BiCMOS工艺。单锁相环，单ssb混频器概念从2.7V电源消耗52mW。带外杂散音调低于-50dBc，允许在2.4GHz和5GHz范围内与WLAN应用协作。集成相位噪声低于2度均方根。测量到的跳频速度远低于所需的9.5ns。

A fast-hopping single-PLL 3-band UWB synthesizer in 0.25/spl mu/m SiGe BiCMOS

A 0.44mm/sup 2/ fully-integrated 3-band MB-OFDM UWB synthesizer in a 0.25/spl mu/m SiGe BiCMOS process are presented. The single PLL, single SSB-mixer concept consumes 52mW from a 2.7V supply. Out-of-band spurious tones are below -50dBc, allowing cooperability with WLAN applications in the 2.4GHz and 5GHz range. The integrated phase noise is below 2 degrees rms. The measured hopping speed is well below the required 9.5ns.
