Proc. 2010 International Microwave Symposium
This paper reflects on design aspects for multichannel
frequency-continuous (FMCW) wave radar frontends from conception to application on board. In the 79-GHz domain,
multi-channel applications are recapitulated, and in the 94-GHz domain, a broadband transceiver is presented along with a voltage-controlled oscillator (VCO) that covers a tuning range of 12 GHz. The functionality of the 94-GHz chipset was verified by means of a four-channel multiple-input multiple-output (MIMO) radar prototype. Finally, a highly integrated 120-GHz transceiver
with on-chip signal generation is presented.
