Sub-millimeter wave diode transceivers
Paper i proceeding, 2014
We present sub-millimeter wave transceiver modules intended for imaging radar applications. In particular a novel circuit architecture that operates in homodyne FMCW radar mode will be highlighted , and the trade-offs between performance and circuit complexity will be discussed. The transceiver units are based on monolithically integrated Schottky diodes fabricated on 3 μm thick membranes. Radar images with 60 dB of signal-to-noise at 220 GHz will be presented as well as design results for a 340 GHz unit.
