This paper presents a 320-GHz 1 x 4 fully integrated phased array transmitter using 0.13-mu m SiGe BiCMOS technology. The 1 x 4 array transmitter is aiming for terahertz wireless communication and is based on RF beam forming architecture. By integrating a 20-GHz phase-locked-loop ( PLL) frequency synthesizer, an 80-GHz quadrupler, a 1: 4 Wilkinson power divider network, four-way 80-GHz tunable attenuators, amplifiers, analog phase shifters, 320-GHz frequency quadruplers/modulators, and on-chip antenna arrays, the transmitter chip achieves a maximal EIRP of 10.6 dBm at 320 GHz with the 3-dB bandwidth of 20 GHz, and +/- 12 degrees beam scanning range is obtained. The dc consumption of the whole chip is similar to 1000 mW and the total chip size is 8 x 4.3 mm(2).
