Raytheon Intelligence & Space successfully demonstrates the integration of Intel System-on-a-Chip in Raytheon’s E-Alpha module.
DARPA selected Raytheon to design, integrate, and demonstrate the capabilities of Intel’s Direct RF FPGA technology as part of the Electronics Resurgence Initiative: Security Application Program.
This demonstration led to the first software defined radio (SDR) using Intel’s Direct RF FPGA technology built into Raytheon’s E-Alpha radio module.
The compact module includes analog and digital components that directly digitize and synthesize RF signals.
Both are crucial for establishing sustainable communications in a joint, multi-domain combat space.
Aaron Maestas, chief engineer for modern concepts and technologies at Raytheon Intelligence & Space, gave a useful analogy to this demonstration: “Imagine standing in a sports stadium – a noisy and crowded environment … with this demonstration we learned how to hear clearly and distinctly a single whisper. “
This module improves response time while increasing functionality. With up to eight high-precision receive and transmit channels, each fully programmable, E-Alpha eliminates complex and expensive RF conversion, filtering and amplification.
E-Alpha can be inserted into various SWaP-limited DoD and commercial applications that require advanced electromagnetic spectrum processing, such as USAF Advanced battle management system.
