Silicon Radar is a technology oriented company that gains a competitive advantage through the application of advanced and cost-efficient IC-design and fabrication technologies.

Silicon Radar develops and delivers advanced, SiGe-based millimeter-wave integrated circuits (MMIC) for wireless communications and radar applications. The main areas of expertise are:

  • Single-chip radar systems,
  • 60GHz communication systems,
  • X-band phased array RF-frontends and power amplifiers, and
  • Terahertz circuits for communications and imaging.

Silicon Radar was founded as a spin-off company by employees of the Leibnitz Research Institute IHP GmbH in June 2006.


Resources: SiR has all the tools for the design of MMICs in SiGe BiCMOS technology including RF-MEMS switches. The design flow includes ADS for circuit design, Momentum for EM-simulation and TexEDA for layout design and verification. SiR has a complete design flow for the development of SiGe BiCMOS circuits with integrated MEMS switches.


Dr. Wolfgang Winkler has many years of experience of developing and successfully delivering RF-circuits based on SiGe. Wolfgang has also published numerous technical papers on the benefits and potential cost savings if using SiGe BiCMOS based solutions. He is the founder of the company “Silicon Radar”. Currently he works as Senior RF designer and CTO in this company. From 1998 to 2007 Wolfgang worked as a design engineer in the IHP in Frankfurt (Oder). His main projects are building blocks for wireless transceivers at 60 GHz and radar circuits at 24 and 122 GHz and design of benchmarking circuits for technology development, characterization and model verification. His recent work includes circuits for frequencies up to 200GHz and he established a new design flow at SiR for RF-circuits in SiGe-BiCMOS including MEMS-switches.


Dr.-Ing. Wojciech Debski received M.Sc. degree from the University of Science and Technology, Krakow, Poland in September 2002, and Ph.D. from the Brandenburgische Technische Universität, Cottbus, Germany in 2007. During his Ph. D. work he developed fully integrated CMOS WLAN receivers operating at 5GHz and 24GHz. In April 2007 he joined Silicon Radar GmbH. He develops RF front-ends for radar applications at 24GHz and 77GHz and transceiver building blocks for frequencies above 100GHz in SiGe BiCMOS technology.
