Abstract

The rapid growth of satellite direct-to-device (D2D) and Internet of Things (IoT) connectivity is driving demand for flexible, compact, and power-efficient satellite payload radios. Supporting direct communication with smartphones and low-power IoT devices presents unique RF design challenges, including challenging link budgets, diverse spectrum requirements, and stringent size, weight, power, and reliability constraints with large phased array antennas.

This white paper explores the key RF design considerations for satellite D2D/IoT service links and demonstrates how Texas Instruments’ AFE8030, a highly integrated, low-power, octal-channel direct RF-sampling transceiver, addresses these challenges. Key capabilities include simultaneous multi-band operation, fast frequency hopping, flexible JESD204 interfaces, multi-device synchronization, simplified antenna calibration, and dynamic power-saving features. Together, these capabilities enable scalable, software-configurable, and power-efficient radio architectures for next-generation satellite connectivity for D2D, IoT and beyond.
