Amalfi Semiconductor of Los Gatos, Calif., a fabless developer of high-performance CMOS radio frequency and mixed-signal semiconductors, today announced that Dan Wark, a former executive of Volterra Semiconductor Corp., has been hired as vice president of operations. Wark brings to Amalfi over 25 years experience in manufacturing for both fab and fabless semiconductor companies. At Volterra, Wark was responsible for all manufacturing activities and was instrumental in implementing a scalable planning infrastructure that enabled the company to grow approximately 50 percent per year over the past seven years, Amalfi said. He was also part of the management team that led Volterra's successful IPO in 2004. Before that, Wark held executive and management positions at Pericom Semiconductor, Linear Technology, Avantek and National Semiconductor. At Amalfi, Wark will be responsible for all product manufacturing activities and will play a significant role in setting up the company's manufacturing operations as it prepares to produce its first product, a CMOS-based power amplifier device for the cellular handset market, expected to be introduced in the first half of 2008.
