An Eight-Element 370–410-GHz Phased-Array Transmitter in 45-nm CMOS SOI With Peak EIRP of 8–8.5 dBm

This paper presents a 370-410-GHz phased-array transmitter, which is based on a W-band distribution network, amplifiers, and vector modulators, feeding a linear eight-element quadrupler array. The quadrupler outputs are connected to high-efficiency microstrip antennas. The design is scalable to a large number of elements, since most of the chip operates at W-band frequencies. The chip is built usi...
