Munich, Germany and White Plains, N.Y., - June 30th, 2003 - Siemens Venture Capital, the strategic investment arm of Siemens AG, Germany, and Sandbridge Technologies, Inc., a leading U.S. based fabless semiconductor company focused on Software-Defined-Radio (SDR) solutions for multi-standard and multi-function wireless terminals, announced Siemens Venture Capital's multi-million dollar investment in Sandbridge's series B financing. The Siemens investment brings the Sandbridge series B total to $22.5 million raised from seven investors including Atlas Venture, Bessemer Venture Partners, China Development Industrial Bank, Columbia Capital, Doughty Hanson Technology Ventures, Infineon Ventures, and Siemens Venture Capital.
