Beamforming SoCs for Low-Cost, High-Capacity Space Communications

Satellite communications are undergoing rapid transformation, with large constellations in Low Earth Orbit (LEO) and beyond, targeting affordable global connectivity. Achieving this vision requires antenna arrays with thousands of elements — but traditional architectures face prohibitive challenges in power, cost, and complexity. This talk will explore how large-scale integration of RF transceivers into beamforming System-on-Chips (SoCs) enables a new generation of scalable satellite networks. By leveraging advanced CMOS technologies, highly integrated beamforming RFICs reduce system power consumption, shrink satellite weight and volume, and simplify payload design. These benefits translate directly into lower launch cost and more affordable global coverage. The talk will also highlight architectural approaches for flexible multi-band operation, which streamline deployment across diverse satellite platforms while reducing overall development cost. Finally, the discussion will touch on considerations for operating in harsh space environments and the broader impact of integration on both satellites and ground terminals. Together, these advances position RFIC integration as a key enabler of commercially viable satellite connectivity at global scale.
