Based on the support from the National Development and Reform Commission for the Low Earth Orbit Satellite XX Phased Array Antenna Production Line Project, the product relies on silicon-based multi-channel RF chips as its core. Through a hybrid PCB process, it integrates the antenna, RF, and control circuits into a complete functional standardized subarray. Depending on the technical specifications required for different antenna sizes, a strategy of standardized subarray assembly is employed to expand the performance of the phased array antenna.
