摘要：

A dual-band up-converter (DB-UPC) for a dual-band direct sequence UWB transmitter is demonstrated in 0.18-mu m CMOS. The DB-UPC translates a base-band UWB pulse to a 3-5GHz low-band or 7-9GHz 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 -8dB, +10dBm in the low-band and -14dB, +14dBm in the high-band respectively.
