Above the Noise

In this episode, Matt Morgan of the National Radio Astronomy Observatory, discusses the challenges of designing ultra‑sensitive, wideband RF systems and the invention of reflectionless filters to improve stability, reduce spurious responses, and absorb out‑of‑band energy.

He explains applications across radio astronomy, mixers, multipliers, and potential use in quantum computing, and describes how fabrication and packaging choices affect performance up to sub‑millimeter wavelengths. Visit Mini-Circuits at www.minicircuits.com.

Andrea Goldsmith, president of Stony Brook University and renowned wireless communications expert, discusses the foundational research behind modern wireless systems, the promise and challenges of 6G and AI, her experience translating academic work into successful startups (Quantenna and Plume), and Stony Brook’s major quantum research initiative supported by a $300M state investment.

The episode covers adaptive modulation and multi-antenna systems, integrated communication and sensing, the economics of next-generation wireless, and the university’s plans to build a terrestrial quantum network, advance quantum computing and sensing, and educate the next generation of scientists.

In the premiere episode of Above the Noise, host Pat interviews Jim Cable, the semiconductor leader behind Peregrine’s RF CMOS breakthroughs. Jim recounts developing silicon-on-sapphire and SOI switches, winning major customers like Murata, and guiding Peregrine through product scaling and acquisition.

They discuss the technical challenges and market strategies that displaced GaAs switches, lessons for startups about disruptive innovation and timing, and Jim’s ongoing advisory work in GaN on silicon, CMOS power amplifiers, quantum, and advanced packaging.
