# Coolstar Technology

> Coolstar Technology designs silicon radio-frequency power amplifiers and front-end chips for Wi-Fi access points and other wireless equipment. Its NovaFET platform, co-developed with TSMC, aims to combine linear RF output with lower heat and easier system integration than conventional gallium-arsenide alternatives. Founder Xiaotong Lin says the company abandoned an early licensing plan when chip-level customization made the economics unattractive.
