Abstract

The design of a high linearity current-mode mixer, which is targeted for base-station (BS) direct-conversion receiver, is described in this paper. Several different configurations based on the Gilbert cell mixer are compared to achieve a high input referred third-order interception point (IIP3) performance with a low noise figure (NF). According to the simulations the designed mixer achieves +15-dBm IIP3 and 10-dB NF. The mixer draws 7 mA from a 2.5-V supply and has been fabricated with a 0.25-mum SiGe BiCMOS process
