摘      要：A frequency synthesizer for the ultra-wide band（UWB） group #1 is *** synthesizer uses a phaselocked 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 *** synthesizer is fabricated in Jazz 0.18-μm RF CMOS *** 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 *** hopping time between different bands is less than 1.8 *** synthesizer consumes 30 mA from a 1.8V supply.
