Advanced Wireless Semiconductor Company is based in Tainan City, Taiwan, and was incorporated in 1998. It researches, develops, produces, tests, and sells gallium arsenide (GaAs) wafers. Its offerings include InGaP/GaAs heterojunction bipolar transistor processes for power amplifiers and gain blocks, GaAs pseudomorphic high electron-mobility transistor processes for switches and low-noise amplifiers, and integrated heterojunction bipolar and high electron-mobility transistor technology for single-chip designs in smartphones and Wi-Fi. It also provides IPD resistor, inductor, and high-Q processes for passive components, optical products such as vertical cavity surface emitting lasers and CPV solar for sensors, 3D sensing, AR/VR, auto drive, and solar power plants, and flip-chip on GaAs wafer CU pillar bump technology to replace wire bonds.
