Spectra7 Microsystems Inc. announced the appointment of Steffen Hahn as Senior Vice President, Engineering. Prior to joining Spectra7, Mr. Hahn ran engineering at Kumu Networks, where he pioneered its unique same-channel 'Full Duplex' technology and designed custom SoCs (Systems on Chip) using silicon on insulator technologies. Before Kumu, he was VP of Engineering at Scintera Networks (now ADI) working on fully stand-alone power amplifier linearization chips.

Prior to Scintera, he was VP of Engineering at Quellan (acquired by Intersil), developing noise cancellation solutions for cellular and handheld GPS as well as high speed equalizer products for copper channels, and at Airgo Networks (acquired by Qualcomm), where he worked on miniaturizing the first WiFi MIMO systems. His early career was spent at Philips Semiconductors on developing the technology and design environment for chips on glass. Mr. Hahn holds an M.S. degree from RWTH Aachen in Germany and has 41 granted patents.
