The University of Stuttgart, in close collaboration with VDI and Keysight Technologies, introduced the Crosslink system, which successfully transmitted a complex modulated signal over a #THz channel. This groundbreaking achievement marks a significant stride toward realizing #6G and its potential for immense data rate availability through the utilization of the terahertz frequency range and its exceptionally high bandwidth. Advancing this technology necessitates ongoing development of precise measurement solutions for evaluating channel performance and distortion between transmitters and receivers. Correcting these distortions is crucial for optimal functionality in 6G applications. Watch the video below to hear from Prof. Ingmar Kallfass of Stuttgart and VDI CEO Tom Crowe to discover more about this collaborative effort propelling us closer to the frontier of next-generation wireless technology!

Thank you, Masoud Agah, for being a strong advocate for Virginia's semiconductor industry! Masoud founded Virginia Alliance for Semiconductor Technology, or VAST, which is a network of private companies and universities working together to provide access to research facilities, training programs, and general support for the growth of our regional semiconductor sector on the global stage. During a recent trip abroad, Masoud even spotted some VDI components while visiting Ljubljana University in Slovenia! #mmWave #THz
Virginia Alliance for Semiconductor Technology (VAST) The first two days in Slovenia was packed with great meetings with academia and industry focused on semiconductor and optics. And yes, Virginia Diodes, Inc. product was in use at Ljubljana University. Meeting the technical leaders at RLS, manufacturer of encoders and associated ASICs, and touring thier facility was wonderful. Traveling to Maribor, meeting with faculty and then a visit to the fiber tower was special. Tomorrow, I will present to government, academia, and industry leaders why “Virginia” is a great place for growing collaborative and innovative buisness especially in chips and microelectronics. #chips #semiconductors #partnerships Virginia Economic Development Partnership VIPC | Virginia Innovation Partnership Corporation

Exciting developments for the future of #6G from Nizar Messaoudi, 6G Program Manager at Keysight Technologies! His latest work combines frequency-stitching with digital-to-analog converters (DACs) to improve ultra-wideband (UWB) signal generation. Use the link below to learn more! #mmWave #THz https://lnkd.in/eUGrvmYa
We’re excited to share our latest research: "Frequency-Stitching-Based Ultrawideband Signal Generation for 6G Component/System Testing: Achieving 12-GHz Instantaneous Bandwidth and 96-Gbps Data Rate at D Band." In this work, we introduce an innovative approach to ultrawideband (UWB) signal generation at millimeter-wave (mmW) and sub-THz frequencies, utilizing frequency-stitching techniques with high-resolution digital-to-analog converters (DACs) operating below twice the target bandwidth. By dividing test signals into subbands and calibrating for seamless phase and magnitude continuity, our method delivers robust, precise signal generation tailored for the demands of next-generation 6G testing. We successfully generated a 256-QAM OFDM signal at D band with a 12-GHz instantaneous bandwidth, achieving an impressive peak data rate of 96 Gbps. Through advanced calibration, we improved signal quality dramatically, reducing the error vector magnitude (EVM) from 82.6% to below 2% and normalized mean square error (NMSE) from 23.8% to under 1%. Additionally, we enhanced the linearization of a D band power amplifier, improving adjacent channel power ratio (ACPR) and EVM for a 4-GHz modulation bandwidth signal from -27.8/-26 dBc and 8.5% to -42.8/-43.1 dBc and 1.2%. This methodology unlocks new possibilities for high-quality UWB signal generation and precise testing in mmW and sub-THz bands, advancing the frontier of 6G component and system testing. A special thank you to my coauthors: Zi Jun Su, Ahmed Ben Ayed, Patrick Mitran and Slim Boumaiza. We also extend our gratitude to Virginia Diodes, Inc. for their support in making this research possible. #6G #Research #Ultrawideband #SignalGeneration #mmWave #SubTHz #RFTesting #Innovation #Wireless
