76 GHz flip-chip MMICs for automotive radars

Abstract

Using the flip-chip bonding technique, we developed a 76-GHz MMIC chip set for automotive radars. A chip set consists of a 76-GHz amplifier, a 76-GHz mixer, 76-GHz SPDT switches, a 38/76-GHz doubler, a 38-GHz voltage-controlled oscillator and a 38-GHz buffer amplifier.
