Phased Array Solution for SATCOM : A Modular Approach

SATCOM ground terminals are rapidly scaling in size and complexity to support LEO and multi-orbit systems, driving phased arrays toward hundreds or thousands of radiating elements. As RFIC count and assembly complexity increase, integration and cost become dominant challenges. This workshop contribution presents a modular Antenna-in-Package architecture for SATCOM terminals, based on a holistic co-design of CMOS beamforming RFICs, antenna, thermal and packaging. The modular approach simplifies array assembly and scalability while preserving RF performance, offering practical insights into system-level trade-offs relevant to next-generation phased array terminal design.
