What Signal Processing Technologies does

Signal Processing Technologies (SPT) is a privately held U.S. defense and commercial R&D firm founded in April 2019 by Joe Farkas and Dr. Brandon Hombs and headquartered in Merrimack, New Hampshire. The company performs contract research and development in signal processing for U.S. government sponsors — including DARPA, the Office of the Under Secretary of Defense (OUSD), the U.S. Air Force, U.S. Navy, and the National Science Foundation — and also takes on subcontracted R&D for commercial communications and industry partners. Work spans the full lifecycle from novel concept through prototyping to productization.

The firm's core technical capabilities sit in communications (5G/FutureG cellular, LPI/LPD waveform design, distributed MIMO, multiuser detection, maritime communications), spectrum sensing, radio frequency machine learning (RF/ML classification, ML-based equalization and decoding), sensor fusion and orientation tracking, alternative position/navigation/timing (PNT) including GPS-denied time distribution, and software defined radio (SDR) testbeds and rapid prototyping. Named products include ARISE (AI Restoration for Impaired Signal Extraction), which uses ML to reconstruct RF signals operating up to 40 dB past the receiver's linear region, and an anomaly detection system covering DC to 6 GHz. The founders bring direct lineage from DARPA programs DIMA, CommEx, BLADE, ARC, POSYDON, and TEAC, and from the 2017 DARPA Spectrum Collaboration Challenge (2nd place).

SPT generates revenue through government R&D contracts and subcontracted commercial R&D engagements on a quote-based, project-scoped basis; no public pricing is disclosed. In February 2026 the firm was named an industry partner on the RTX/BBN Technologies-led Advanced Spectrum Coexistence Demonstration program under the U.S. Department of War, and in 2026 it was acquired by Code Metal, ending its status as an independent private company.
