Abstract :
A 0.44mm2 fully-integrated 3-band MB-OFDM UWB synthesizer in a 0.25μm 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.
