Raytheon Technologies Now Involved in Radio Frequency Mixed-Mode Circuit Designs for DARPA

May 6, 2020

Raytheon Technologies (NYSE: RTX) is researching advanced radio frequency mixed-mode circuit designs, under DARPA’s Technologies for Mixed-mode Ultra Scaled Integrated Circuits, or T-MUSIC, program.

These systems operate much the same way humans do. The front end of the system is like eyes and ears, and the back end is like the brain. The brain processes what the eyes see and ears hear. And, in order for the back end to provide actionable information, the front end must be able to discriminate between the noise and the signals of interest.

This is driving the need for multi-function systems with mixed-mode electronics at the front-end of the system, which convert the RF signal into bits. Those bits are vital pieces of data that the back-end processes, improving the ability to distinguish between the noise, interference and signals of interest across a broad range of frequencies.

The overall benefit is not just small size, weight and power – it’s the performance. The technology would be able to detect the faintest of signals among a broad range of frequencies and noise, processing it with precision and speed. It could identify the object emitting the signal, even if it’s slow-moving or very small.

The designs are being collectively researched by Raytheon, commercial, aerospace and defense companies and universities. The designs could form the foundation out of future Department of Defense-relevant capabilities, including communication links, multi-function RF systems and next-generation electronic warfare and radars.

Art Morrish, VP of Advanced Concepts and Technologies at Raytheon Intelligence and Space, a Raytheon Technologies company, noted that radio frequency bands are increasingly cluttered — we need to be able to ‘hear’ through all of the noise. If someone is yelling at you, it’s easy to miss what someone else is whispering. However, imagine if you had a way to hear both at the same time. That’s what the company’s multi-function system with mixed-mode electronics seeks to achieve. What’s different here is all of this could happen on a single chip — nobody has done this type of mixed composition before.
