Shenzhen SDSX Technology Co., Ltd. (“SDSX”) has closed a several-hundred-million-RMB Series D round jointly funded by the Liangxi District Government of Wuxi and Wuxi Liangxi Sci-Tech Industry Investment Phase-II Fund Partnership (L.P.), also known as Bohua Capital. The proceeds will accelerate R&D and mass-production of RF chips and modules for next-generation satellite-internet applications and finance the construction of SDSX’s R&D and manufacturing base inside the Liangxi Satellite-IoT Industrial Park. The partnership formally integrates SDSX into Liangxi’s “space-air-ground” industrial ecosystem, positioning the company as a core contributor to the district’s “Liangxi Chip,” “Liangxi Rocket,” and “Liangxi Constellation” initiatives.

Government and capital join forces to chart a new aerospace roadmap

This partnership efficiently fuses strategic policy with market capital. Guided by Wuxi’s “465” modern-industry-cluster initiative, Liangxi District is actively building a “constellation” economy: targeting the satellite track, amplifying cluster effects, and strengthening every link of the full “rocket-satellite-spacecraft” chain. The district’s roadmap is anchored in three pillars—“Liangxi Rocket” (launch-vehicle manufacturing), “Liangxi Constellation” (satellite production & deployment), and “Liangxi Chip” (core components)—to create a seamless space-air-ground ecosystem. SDSX’s establishment in Liangxi, backed by Bohua Capital’s investment, is a decisive response to this vision, injecting the chain with home-grown RF chip technology that will underpin every future “Liangxi Star” and “Liangxi Arrow.”

Taking “Chip” as the Core, Connecting Heaven and Earth with Responsibility

As a national-level “Specialized, Refined, Distinctive and Innovative” key “Little Giant” enterprise and a private-sector leader in RF/microwave chips and modules, SDSX covers the full critical chain—chip design, module development, packaging & testing, and quality assurance. Since inception the company has delivered several thousand fully home-grown chips now deployed in satellite-to-ground communications, special-purpose networks, automotive electronics, the domestic C919 program, and 5G base stations. In the space segment alone, SDSX products have been qualified for flight and are already on board dozens of low-Earth-orbit satellites. Its latest generation—an 8-beam, 32-channel satellite payload chip—achieved first-silicon success on the first pass, making SDSX the first supplier to offer a complete 8-beam transceiver solution and propelling a generational upgrade of the nation’s LEO constellation microwave payloads.

Going forward, SDSX will leverage Liangxi’s unrivaled aerospace ecosystem, the district’s strategic backing, and Bohua Capital’s financial strength to keep expanding R&D and rapidly scale capacity. The company will become a vital “chip” piece of the Liangxi “Constellation” vision, striving to evolve into a world-leading semiconductor enterprise. With every high-performance “Liangxi Chip,” SDSX will power the national space-air-ground integrated information infrastructure and contribute core strength to China’s journey toward indigenous chip innovation and global leadership.
