Abstract
Graphene has been targeted for a wide variety of applications due to its characteristics. It is a zero-bandgap material, has high conductivity, and high carrier mobility, which makes it a promising material for radiofrequency applications. This review examines the applications of graphene in the design of radiofrequency building blocks, their performance, and current hurdles. Initially, graphene passive devices (inductors, capacitors, antennas, and waveguides) are analyzed, as well as their current modelling techniques. Then, radiofrequency transistors and their modelling are reported and discussed. An insight on the current state of radiofrequency devices is provided which more specifically targets graphene oscillators, multipliers, and mixers. Finally, the current fabrication issues and techniques are analyzed and discussed, providing a global overview on the application of graphene for radiofrequency electronics.
