This paper presents a chipset aiming at high resolution imaging systems for real-time people screening applications operating near the W-band. The frequency of operation ranges from 70 GHz to 82 GHz for optimal image resolution and depth of focus. The frequency generation for both receiver and transmitter chips consists of a mixer based frequency quadrupler(More)
This paper presents a D-band transceiver front-end with twin quadrature receivers fabricated in a low cost 0.35μm SiGe bipolar production technology, featuring HBTs with fT/fmax of 200/250 GHz. The receiver achieves a minimum single-sideband noise figure of 14 dB, conversion gain greater than 23 dB and an input-referred 1-dB compression point of -9(More)
