Delaware Patent of the Month – November 2023

Radio frequency (RF) signal processing is taking a leap forward, thanks to the recently patented innovation by Phase Sensitive Innovations, Inc. (PSI). Their latest invention unveils a method that transforms the landscape of RF receivers, ushering in a new era of dynamic range and interference mitigation.

In a nutshell, PSI’s method involves a sophisticated dance of optics and RF wizardry. It all starts with an array of antenna elements receiving RF signals, each element generating an RF electrical signal in response. This leads to an intricate process of modulating an optical carrier beam with the RF signals, creating a symphony of upconverted optical signals.

These optical signals then move through a transmission array—a group of optical waveguides arranged in a strategic pattern. As they converge in an interference space, they form a composite beam.

The sensor array, a collection of lens-coupled single-mode optical waveguides , is positioned in a detection plane. These sensors are not mere spectators; they are integral participants. As the composite beam interacts with them, a vivid RF emitter interference pattern emerges, capturing the essence of the RF signals.

What sets PSI’s invention apart is its ability to handle multiple RF signals simultaneously. The spatial arrangement of the antenna elements and optical waveguides orchestrates a symphony of interference patterns, providing a comprehensive view of the RF spectrum.

PSI introduces a reference optical beam into the mix, fine-tuning the precision of the process. The result is not just a method; it’s an art—a precise, dynamic, and scalable approach to RF signal processing.

PSI has specialized in the design, fabrication, and manufacturing of photonic devices. By developing the technology and integrating it within numerous RF systems, they have achieved both 5G and B5G wireless communication as well as numerous other applications.
