This paper presents a compact and low-power D-Band four-quadrant active phase shifter using meandered λ/2 transmission-lines (TLINEs) for phase inversion. TLINE impairments (loss and phase deviation from 180°) are analyzed and their effects on the output vector space are discussed. A calibration technique is applied such that the phase shifter RMS amplitude and phase errors are kept under 1.2dB and 8°, respectively. Implemented in SiGe BiCMOS 55 nm, the proposed circuit covers 130- 175 GHz bandwidth with -4.5dB peak gain, $\mathrm{O}\mathrm{P}_{\mathrm{1}\mathrm{d}\mathrm{B}}$ greater than -3dBm and 20mW average power consumption.
