INRS-EMT Millimeter Wave Laboratory: Circuits, Modules and Interferometric Systems

The presentation highlights the use of interferometric techniques in millimeter wave systems such as high data-rate communication systems, radar sensors or broadband quadrature interferometric mixers. The main advantage of these mixers, compared to conventional ones, are the reduced power requested for the operation. The fabrication technologies used are MHMIC, RW, SIW. All circuits and modules are designed and characterised in our millimeter- wavelaboratory. Fabrication uses outside facilities. As an initial step, computer models based on the VNA measurements are used in computer simulations of the systems to validate the architecture and functionality. This allows important cost reduction on module/transceiver prototypes. Test benches and some measurement results of the fabricated prototypes, from 24 GHz up to 90 GHz are presented and discussed. Future work will include designs at higher frequency, over D-band (110 – 170 GHz), to meet the ongoing requirements of the academia and industry.
