Abstract :
A dual-band up-converter (DB-UPC) for a dual-band direct sequence UWB transmitter is demonstrated in 0.18-mum CMOS. The DB-UPC translates a base-band UWB pulse to a 3-5 GHz low-band or 7-9 GHz high band. The DB-UPC consists of two mixers followed by a combiner. The high and low band mixers consist of a fully differential mixer core followed by a differential to single-ended converter. The DB-UPC has linear transfer characteristic for up to 0.7Vpp input pulse amplitude. Measured voltage gain and two-tone IIP3 of the DB-UPC are -8 dB, +10 dBm in the low-band and -14 dB, +14 dBm in the high-band respectively.
