With the rapid advances in graphene field-effect transistor (GFET) performances, graphene has attracted much interest as a future channel material in RF electronics. However, the pace of the development of graphene circuits seems significantly slower. Several graphene circuits demonstrated today showing promising GHz functions still relied on ideal discrete passive components connected at the equipment...
This work presents recent advances in the development of graphene technology for various applications from RF to THz frequencies. First, large-scale graphene synthesis methods are reviewed. Graphene FETs suitable for RF applications are then presented along with their DC and RF characteristics. The challenges and current progress toward wafer-scale integration of graphene-based RFICs are also discussed...
