Abstract
This paper presents a D-band (130-170 GHz) phaseshifter design for an inherently scalable transmitarray topology. The design is optimized for low-power consumption by utilizing a single-ended active vector modulator designed as an amplifier and proper sizing of the input and output amplifier transistors. The chip is fabricated using 0.13-μ m SiGe BiCMOS technology and achieves a measured maximum gain of 27 dB across the full phase range. Additionally, it demonstrates a 1-dB compression point of -5 dBm, with a power consumption of only 76 mW.
