Abstract

A 77GHz MMIC transceiver module has been developed for automotive radar applications by using a low-cost thick-film multi-layer ceramic substrate. The module accommodating all MMIC-based transceiver functions in a single-cavity housing for improved manufacturability can be either assembled with built-in Tx/Rx antennas or mounted on external antenna sheet, depending on required antenna beam width. The module, measuring 25/spl times/25/spl times/3.4mm/sup 3/ with 3.3g in weight, has demonstrated >150m target detection capability when evaluated in a radar system, compatible with our current production-type radar.
