Radio-frequency Matrix-Vector Multiplication: An Analog Computing Proof of Concept

Fadi Farag, Dominic Stewart-Guido, Ishaan Vohra

MIT 6.2300 (Electromagnetic Waves and Applications) Final Project, 2025

  • Project goal/objective: Proof of concept for matrix-vector multiplication (linear analog computing) in the RF domain in a highly compact and cost-efficient setup, useful for applications in low-latency signal processing.
  • Technologies used: Keysight ADS (RF PCB design), TXLine (RF PCB design), CNC milling machine (PCB fabrication), soldering under microscope.
  • Deliverables: Fabricated hardware matrix-vector multiplier, presentation given before RF/photonics industry judges.
  • Other notes: This presentation opened up the possibility of a 2025 summer research internship at Analog Photonics for my team and I! Unfortunately I already had committed to another project in MIT RLE’s Quantum Photonics and AI Group, so I couldn’t pursue the opportunity further.
