This round of financing was led by "Financial Street Capital," with follow - on investments from existing shareholders "SDIC Venture Capital" and "Shanjin Capital," and participation from "Huaxi Securities" and "Shenzhen Investment Holdings" and other capital sources. The funds raised will mainly be used for mass delivery and production preparation of RF microwave chips and modules, construction of SiP advanced micro - assembly production lines, and research and development of next - generation RF microwave chip technologies. This will further consolidate SDSX's leading position in the field of RF microwave chips and modules.

The company focuses on the research and development of RF microwave chips and is one of the few domestic suppliers that can provide fully domestic, independently controllable Si RF, second - and third - generation compound semiconductor RF microwave chips and modules. With a research and development team of over a hundred people, the company has independently developed a series of products such as RF microwave chips, microwave integrated circuits, and low - cost millimeter - wave SiP modules, based on years of technical accumulation and its own technological advantages. The company's products cover the L - to W - band and are mainly used in private networks and satellite communications. They can also be applied to 5G communications and new energy vehicles, with some products reaching international advanced levels.

The company has always adhered to the development strategy of "specialization, refinement, uniqueness, and innovation." It has obtained more than a hundred authorized patents (including 53 invention patents), covering the entire process of chip design, mass production, and testing. It has been recognized as a "specialized, refined, unique, and innovative" enterprise and has become the first domestic RF chip company to obtain the automotive - grade AEC - Q100 certification for RF chips and to be equipped in new energy vehicles.

The company's headquarters is located in Shenzhen, with four subsidiaries in Chengdu, Shanghai, Beijing, and Nanjing. The Shenzhen headquarters and Chengdu R & D center have a 3,000 - square - meter top - notch domestic chip R & D laboratory and high - specification experimental certification environment. They can provide customers with high - performance, high - reliability products in a long - term, stable, and rapid manner. The company continues to strengthen its production capacity. The 6,000 - square - meter SiP advanced micro - assembly production line in the Tianfu New Area of Chengdu has been built and put into operation. It will provide strong support for the demand of RF microwave chips and modules in the fields of private networks, satellite communications, 5G communications, and new energy vehicles. SDSX adheres to the concept of scientific and technological innovation and a strong country through science and technology, contributing to the high - quality development of the national RF microwave industry.
