On April 23rd, Dr. Gernot Hueber, Head of Re­search Unit RF (= Radio Frequency) at Silicon Austria Labs (SAL), gave a lively talk on tech­nical inno­va­tions for beyond 5G wire­less commu­ni­ca­tion networks in Vienna.  On this occasion, he delivered expert insights in SAL's innovation approach in the field of mm-Wave & Radio Frequency.

Re­search projects at SAL in the mm-Wave/​RF domain are targe­ting tech­nical inno­va­tion for beyond 5G future wire­less commu­ni­ca­tions networks. The re­search team, headed by Gernot Hueber, deve­lops specific back­haul/​front­haul appli­ca­tion and devices opera­ting in the 300 GHz frequency bands. Bitrates excee­ding 100 Gb/​s, cost-effi­ci­ency, high spec­trum and power effi­ci­ency are the main features of the next gene­ra­tion RF front-ends. These features will be enabled by the key tech­no­lo­gies, which are developed in SAL research projects.

High-performance systems with low maintenance costs

System topologies and RF components will be the key elements within the development envisaged together with project partners in the EU. A scalable and modular system architecture including packaging will enable cost-effective mass production of 300 GHz lens array antenna front-ends. The parallelization of data streams using multiplexing architectures such as line-of-sight MIMO, frequency carrier aggregation and polarization multiplexing will boost energy and spectral efficiency. A novel beam alignment concept by using agile lens antennas allows automatic adjustments during life time, resulting in a significant reduction of installation/maintenance cost. By considering the design of the complete architecture, from antenna down to baseband, a high-performance system is guaranteed as research outcome.

The power of sub-mm-Wave communication platforms

SAL will focus on beyond 5G scenarios: backhaul (point-to-point), fixed wireless access (point-to-multipoint), and access networks in crowded scenarios (point-to-multipoint). Demonstrations addressing these three scenarios will clearly show, how powerful and flexible the sub-mm-Wave communication platforms are.

Bio of Gernot Hueber

Gernot Hueber received the Dipl.-Ing. degree (Master) in Mechatronics and the Dr. techn. degree (Ph.D.) from the Johannes-Kepler University Linz, Austria, in 2000 respectively 2006.

In 2018, Dr. Hueber joined Silicon Austria Labs, where he is Chief Scientist for RF and leading the Research Unit RF.

From 2011 to 2018, he was System Architect for NFC controller products with NXP Semiconductors Austria.

From 2006 to 2011, he was with DICE GmbH & Co KG, a subsidiary of Infineon Technologies, where he managed the RF Innovations group conducting the research on circuits and systems for cellular transceivers.

From 2000 to 2006, he was with the Research Institute for Integrated Circuits (RIIC), where he investigated RF front-ends for multi-mode cellular terminals.

His re­search inte­rests include the design of radio frequency inte­grated circuits for commu­ni­ca­tions appli­ca­tions with a focus on phased-array, beam-forming, MIMO, advanced RF archi­tec­tures, digital enhanced analog/​RF, adap­tive digital signal process­ing, and opti­miza­tion tech­ni­ques.

Dr. Hueber has published two edited books (the recent one on “Milli­meter-Wave Circuits for 5G and Radar”), more than 80 journal and confe­rence publi­ca­tions, work­shop presen­ta­tions, and filed 70+ patent appli­ca­tions in US, EU, CN, KR, JP. Dr. Hueber was awarded the "Talent­för­de­rungs­prämie 2007" from the Upper Austrian Govern­ment, the EEEfCOM Award 2007 and the No. 1 Article in EETimes RF/​Micro­wave Desi­gn­line 2010.

In 2008, Gernot Hueber formed the IEEE Austria Circuits and Systems/​Solid State Circuits Joint Chapter. He is serving the commu­nity e.g., as TPC Chair (ESSCIRC 2015), Stee­ring Committee Member and TPC Member (RFIC Sympo­sium) and Reviewer for multiple jour­nals (JSSC,  TMTT, TCAS, etc.).
