Leveraging 35-nm InGaAs mHEMT technology, the project developed key components including frequency multipliers, mixers, and amplifiers, achieving robust performance across the 250'\u2013325 GHz band. These circuits demonstrated high gain, wide bandwidth, and strong linearity '\u2014 essential characteristics for meeting the demanding requirements of THz communication in complex environments. In parallel, cutting-edge antenna solutions were developed. High-gain lens antennas achieved over 50 dBi with extremely narrow beamwidths below 0.65'\u00b0, while beam-steering antennas demonstrated directional control from 0'\u00b0 to 45'\u00b0 with gains up to 26 dBi. These antennas are critical enablers for focused, long-range THz links, and they align with the project'\u2019s key performance indicators and proof-of-concept goals. The project also established a methodology for characterizing Reconfigurable Intelligent Surfaces (RIS) at THz frequencies. This involved assessing RIS-induced power losses by measuring the performance gap between specular and non-specular reflections. Using angular-resolved techniques, the RIS transfer function '\u2014 capturing the angle-of-arrival (AoA) and angle-of-departure (AoD) response '\u2014 was extracted to serve as input for the modeling and validation of RIS-assisted THz links","references":"Deliverables 5.1, 5.3 and 5.4 http:\/\/www.times6g.eu\/deliverables","category":"CAT-1: Significant Technology Development","sub_categories":"Hardware;High-frequency Technologies;Micro-Electronics \/ Photonics;","call":"Call 1"},"_links":{"self":[{"href":"https:\/\/wp.eurestools.eu\/fr\/wp-json\/wp\/v2\/key_achievement\/27885","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/wp.eurestools.eu\/fr\/wp-json\/wp\/v2\/key_achievement"}],"about":[{"href":"https:\/\/wp.eurestools.eu\/fr\/wp-json\/wp\/v2\/types\/key_achievement"}],"wp:attachment":[{"href":"https:\/\/wp.eurestools.eu\/fr\/wp-json\/wp\/v2\/media?parent=27885"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
