Abstract
Two low-power D-band receiver front-ends with competitive performance for radar and imaging applications are presented. The receivers include passive and active singleended-to-differential converters realized as an ultra-compact Marchand-based balun and as a differential-pair-based active balun, respectively. The receivers achieve measured conversion gains (CG) of 24.9dB at 134GHz (active balun) and 20.27dB at 124GHz (passive balun) while consuming 425mW and 330mW correspondingly. A wide bandwidth of 32GHz is achieved for the active variant in the 114-146GHz frequency range while the passive approach achieves a CG $\gt 10dB$ in the 112-147GHz frequency range. The passive approach achieves a peak conversion gain of 20.$27dB at 126GHz. The presented results offer competitive performance and compare favorably to reported receiver front-ends in terms of ultra-small silicon area (0.14 and 0.$1mm^{\mathbf{2}})$. The front-ends are suitable for integration in highly-integrated D-Band radar receiver arrays as well as for high-density imaging arrays.
