SiGe Semiconductor sized up the wireless semiconductor market and made its move. The fabless chip company designs radio-frequency (RF) semiconductors used in wireless communications gear. Its WiMAX and Bluetooth power amplifiers, RF front-end devices, GPS receiver chips, and other chip products are used to link laptops, printers, phones, and cameras; enable wireless gaming and streaming video; and provide GPS location and mapping services. Its chips are made from silicon germanium (SiGe), which offers better performance than chips made from silicon alone. Most of its sales come from Asia. SiGe Semi filed for an IPO in 2010; it was acquired by Skyworks Solutions the following year for about $275 million.
