Abstract :
This paper presents a voltage controlled phase shifter in a 0.25 ¿m SiGe BiCMOS technology for 60 GHz applications. Vector combination technique is adopted in phase shifter core. Continuous 360 degree phase tuning from 40 GHz to 70 GHz has been measured. The insertion gain of the complete test circuits is 4.6 dB and that of the phase shifter core is 7.6 dB. The phase shifter is best suited for 60 GHz phased array systems. To the authors´ knowledge, this is the first phase shifter of this type for 60 GHz applications.
