Behavioral Mixer Model for Rapid System Simulation of a 77GHz FMCW-Radar Transceiver

An advanced behavioral model of a 77 GHz SiGe Gilbert-type double balanced mixer is proposed, which is able to accurately model conversion gain compression and noise figure compression due to LO-power drop. The model is for use in system simulation of direct conversion automotive FMCW-radar transceivers. Model parameters can be easily extracted from 77 GHz measurement data. The model has been validated with measurement data and circuit level simulations and can be implemented in commercial simulators.
