摘要

MMIC芯片组已开发用于77 GHz双工雷达配置的前视防撞雷达(CAR)。该芯片组采用可用的MMIC代工工艺设计，使用0.18和0.10 /spl mu/m t栅PHEMT技术。双工雷达相对于CAR应用中常用的FMCW和FSK方法具有一定的优势。例如，由于这种方法允许对振荡器的相位噪声要求不那么严格，因此可以将通用的MMIC工艺用于所有MMIC设计。完整的MMIC模块已经完成了77 GHz的接收和发射特性评估，目前正在等待道路测试。

77 GHz MMIC T/R module for diplex radar application in collision avoidance radar (CAR)

A MMIC chip set has been developed for use in a forward-looking Collision Avoidance Radar (CAR) at 77 GHz with diplex radar configuration. The chip set is designed with available MMIC foundry processes using a mix of 0.18 and 0.10 /spl mu/m T-gate PHEMT technology. The diplex radar has certain advantages over FMCW and FSK methods commonly adopted in CAR applications. For example, since this method allows for less stringent phase noise requirements on the oscillator, a common MMIC process can be used for all of the MMIC designs. The complete MMIC module has been evaluated for receive and transmit characteristics at 77 GHz and is presently awaiting road testing.
