A paper published in the journal Nature Communications back in 2014 — entitled, “Graphene radio frequency receiver integrated circuit” — explains how graphene has “superior electrical properties” and has strong potential as “a future channel material in radio frequency electronics.”
“Fabrication of a graphene integrated circuit without significantly degrading transistor performance has proven to be challenging, posing one of the major bottlenecks to compete with existing technologies,” the study’s abstract reads.
“Here we present a fabrication method fully preserving graphene transistor quality, demonstrated with the implementation of a high-performance three-stage graphene integrated circuit.”
That fabrication method, we now know, involves the use of nearly nanoscale-sized circuit components that are assembled for the purpose of radio signal amplification, filtering, and down-conversation mixing.
As the study explains, graphene was successfully used in experiments to “perform practical wireless communication functions, receiving and restoring digital text transmitted on a 4.3-GHz carrier signal.”...<<<Read More>>>...
