Abstract :
In this paper, an ultra-wideband down-conversion resistive ring mixer is designed using the mixed-mode TSMC CMOS 0.18-mum technology. This mixer down-converts RF signals in the range of 1-11 GHz to fixed IF of 500MHz using LO signals at 500MHz higher than the corresponding RF frequencies. The conversion loss within this band is 7plusmn0.5dB. The input 1dB compression point (P1dB) for the entire band is about 5dBm, and the input third order interception point (IIP3) is about 10dBm. The LO power required to obtain lowest conversion loss for this resistive mixer is 9dBm. The mixer core has no power consumption whereas the IF output buffer consumes 3mW. This mixer can be used in high dynamic range low-power ultra-wideband communication systems
