Abstract :
A 76.5 GHz GaAs MMIC I-Q vector modulator employing two bi-phase reflection-type attenuators is presented. It exhibits a minimum measured insertion loss of 12 dB and occupies an area of 2/spl times/1.6 mm/sup 2/. Using the vector modulator, we introduce the concept of software radar for automotive collision avoidance.
