湖南斯北图科技有限公司 Tech Stack

Satellite communications and 5G/LTE baseband hardware engineering

Research Services 长沙市, 湖南省

Sibtu develops satellite communication systems and terrestrial wireless basebands, with active work on laser signaling algorithms, 5G NTN protocols, and FPGA modules. The tech stack (Cadence, MATLAB, Verilog, ModelSim, SolidWorks) and project list signal a hardware-forward company bridging RF/analog design with digital baseband—evidenced by parallel tracks in laser comms, satellite payloads, and 5G base-station protocol design. Engineering dominates headcount and hiring, with production/manufacturing pain points (batch industrialization, changeover time, reliability traceability) pointing to early-stage mass-production scaling.
