WP5 results for the year 3

The work in WP5 during the period was focused on the characterization of the circuits implemented in the second and third design cycles, as well as the design and optimization of circuits and test structured for the third design cycle, which include the Dotfive demonstrators. Setting up the required infrastructure for the final demonstrators was also part of the activity during the period.  Inter-workpackage activities included characterization of WP4 HBT and passive test structures using WP5 test facilities (UoW 110-170-GHz and 220-320 GHz S-parameter measurement setups).

During the period, IMS worked on the development and characterization of VCOs at and above the 160GHz Dotfive target frequency. JKU continued the development and evaluation of signal generation and radar front-ends using the IFX technology and will present the results on successful 120-GHz circuits in conference and journal publications during the autumn.  The work at UoW focussed on improving the performance of the already successfully demonstrated 160GHz imaging circuits using the updated Dotfive technologies made available during the period. Another direction pursued at UoW was the increase of the complexity of the imaging circuit to include multiple channels, as well as the demonstration of imaging circuits at frequencies above the initial Dotfive targets with results published at conferences and journals during the period. UoS has demonstrated high-resolution security imaging using the UoW Dotfive receiver chips.
