Abstract :
A fully integrated 77GHz 4-element phased-array transmitter in 0.12mum SiGe BiCMOS based on a continuous local phase shifting approach is presented. Each element generates +12.5dBm output power at 77GHz and has 34dB gain from baseband to RF with a bandwidth of 2.5GHz. The chip demonstrates successful beam-steering at 77GHz
