Radio-Frequency Electronics Group
NIST Communications Technology Laboratory’s Radio-Frequency Electronics Group develops fundamental metrology and standards to help industry build better wireless systems through a deeper understanding of how electromagnetic waves interact with the materials and components destined for next-generation 5G wireless, spectrum-sharing and other advanced wireless systems.
Our work has taken on increasing importance as device speeds have advanced into the tens and hundreds of gigahertz, leaving less and less tolerance for error. There’s also a growing need for traceability along the complex path from electrical impulse to the transmission, reception and reconversion to electrical impulse on the receiving end. The RF-materials interactions in which we have long specialized are increasingly relevant sources of error and uncertainty in very-high-speed wireless systems we’ll depend on in addressing the spectrum crunch.
The group’s research in RF-materials interactions seeks to establish precise scientific foundations upon which industry can more quickly develop new materials for front-end filters (which capture a slice spectrum for digital conversion), components capable of harnessing – rather than suffering from – nonlinear transistor behavior, and for components that avoid or suppress thermal and other noise that can degrade transmitters and receivers.
