Problems solved by technology

[0003] Satellite mobile communication systems are limited by satellite launch costs, chip tape-out costs, and the number of users. At present, there are very few companies developing their RF transceiver chips. Most of the chips are designed for proprietary systems and cannot support variable bandwidth or multi-mode functions. , and terminal solutions based on it are also difficult to adapt to the application requirements of various forms of satellite mobile multi-mode terminals
