| Abstract: | A frequency synthesizer for the ultra-wide band(UWB)group # 1 is proposed.The synthesizer uses a phase locked loop(PLL)and single-sideband(SSB)mixers to generate the three center frequencies of the first band group by mixing 4224 MHz with ±264 MHz and 792 MHz,respectively.A novel multi-QSSB mixer is designed to combine the function of frequency selection and frequency conversion for low power and high linearity.The synthesizer is fabricated in Jazz 0.18-μm RF CMOS technology.The measured reference spur is as low as-69 dBc and the maximum spur is the LO leakage of-32 dBc.A low phase noise of-110 dBc/Hz @ 1 MHz offset and an integrated phase noise of 1.86°are achieved.The hopping time between different bands is less than 1.8 ns.The synthesizer consumes 30 mA from a1.8 V supply. |
