Maxscend
Suzhou MAXSC Microelectronics Co., Ltd., founded in 2012 and headquartered in Wuxi, Jiangsu Province, is a leading RF front-end chip design company in China, listed on the Shenzhen Stock Exchange in 2019 (Stock Code: 300782). Specializing in RF integrated circuits, the company provides RF switches, low noise amplifiers (LNAs), filters, and RF modules for smartphones, wearables, communication base stations, automotive electronics, etc., serving global Android handset manufacturers including Samsung, Huawei, Xiaomi, vivo, and OPPO. As one of the few domestic firms capable of full-process RF module design, MAXSC has transitioned from a Fabless to Fab-Lite model through self-built 6-inch SAW filter and 12-inch IPD filter fabs. In 2024, the company achieved revenue of ¥4.487 billion, with RF modules accounting for 42.05% of sales. High-end products like L-PAMiD modules (integrated LNAs and PAs) have entered mass production for major brands.
