This letter presents a <inline-formula> <tex-math notation="LaTeX">${D}$ </tex-math></inline-formula>-band two-element phased-array receiver (Rx) front end implemented in a 0.13-<inline-formula> <tex-math notation="LaTeX">$\mu \text{m}$ </tex-math></inline-formula> SiGe BiCMOS process. The Rx employs a low-loss quadrature-hybrid-based power-domain phase interpolator for a power-efficient multibit phase synthesis. The measured average gain is 13 dB with a peak gain of 15.6 dB at 115 GHz and rms gain variation over 4-bit phase states is <1.6 dB. The measured rms phase error is <5° at 115 GHz. The overall dc power consumption (<inline-formula> <tex-math notation="LaTeX">$P_{\mathrm {diss}}$ </tex-math></inline-formula>) of the single Rx channel is 53 mW from 2.2-V supply. The core chip size of the two-channel Rx is <inline-formula> <tex-math notation="LaTeX">$1.7 \times 1.24$ </tex-math></inline-formula> mm<sup>2</sup>.
