Abstract :
Initial results for a 94-GHz integrated monopulse receiver are presented. The receiver is based on a 23-GHz local oscillator driving four separate phase-coherent 94-GHz subharmonic mixers, and performs monopulse processing on the IF signals. All circuits are integrated on a single wafer, and are realized using uniplanar coplanar waveguides (CPW), slot lines, and coplanar striplines (CPS). These features result in a compact, low-cost system suitable for tracking systems operating in poor visibility conditions, as well as in collision avoidance receivers for automotive applications.<>
