Development of 76 GHz Single Chip MMIC High Frequency Unit

In recent years, various automotive manufacturers have focused attention on in-vehicle millimeter wave radar as a key component for ACC (adaptive cruise control) systems. We have developed the millimeter wave unit core-component of the radar system to make the product more attractive, following on 76 GHz millimeter wave radar development in 2000. Specifically the unit is composed of 2 MMIC (monolithic microwave IC) modules one of which integrates into a single chip MMIC 4 out of the previous 5 MMIC modules, thus rendering the unit more compact, lower cost and better suited to mass production. This paper discusses this 2 module millimeter wave unit incorporating the single chip MMIC unit.
