| Abstract: | A low power and low voltage down conversion mixer working at K-band is designed and fabricated in a 0.13/spl mu/m CMOS logic process. The mixer down converts RF signals from 19GHz to 2.7GHz intermediate frequency. The mixer achieves a conversion gain of 1dB, a very low single side band noise figure of 9dB and third order intermodulation point of -2dBm, while consuming 6.9mW power from a 1.2V supply. The 3-dB conversion gain bandwidth is 1.4GHz, which is almost 50% of the IF. This mixer with small frequency re-tuning can be used for ultra-wide band radars operating in the 22-29GHz band. |
