据《电子材料》(日)2009年第8期报道,NEC公司业界首次采用Si基GaN器件研发了76 GHz的毫米波车载防撞雷达。车载防撞雷达系统成本高,这是不能普及的主要原因。为了降低系统成本,必须降低RF毫米波模块的成本。此次
According to “Electronic Materials” (Japan) No. 8, 2009 reported, NEC company industry for the first time using Si-based GaN devices to develop a 76 GHz millimeter-wave automotive anti-collision radar. Car anti-collision radar system, high cost, which is the main reason can not be universal. In order to reduce the system cost, the cost of RF millimeter wave module must be reduced. This time
