Abstract :
A 77-GHz phased-array radar transmitter that is based on fully integrated, differential, cascadable transceiver circuits is presented. The building blocks of the 77-GHz IQ transceiver are explained in detail, along with measurement results of the transmitter part. A demonstration of the beam-forming capability of the presented transceiver is given using a 4-channel phased-array radar demonstrator that incorporates the generation of PLL stabilized 77-GHz signals.
