Description

This item was taken from the IEEE Conference ' 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.
