Wolfgang Heinrich received the PhD and Habilitation degrees in 1987 and 1992, respectively, from the Technical University of Darmstadt, Darmstadt, Germany. Since 1993, he has been with the Ferdinand-Braun-Institut (FBH) at Berlin, Germany, where he is the Head of the Microwave Department and the Deputy Scientific Director of the institute. Since 2008, he has been also Professor with the Technical University of Berlin. He has authored or coauthored more than 450 peer-reviewed publications and conference contributions. His present research interests include MMIC design with an emphasis on GaN and InP power amplifiers, as well as mm-wave and sub-mm-wave integrated circuits and packaging.

Title of the presentation:
Hetero-Integration of Bipolar InP Chiplets on BiCMOS for Broadband Applications within the
EU-Funded APECS Pilot Line

Abstract:

The paper presents a hetero-integration approach combining InP-HBT chiplets with BiCMOS chips through a microbump flip-chip scheme. The interconnects offer more than 200 GHz bandwidth, the InP process allows to realize MMICs with a transistor fmax of more than 500 GHz, which qualifies it for both D-band transceivers and high-data-rate drivers and transimpedance amplifiers. The platform is being developed in the framework of the APECS pilot line funded by the EU and the German government. It will be made accessible to external partners.
