▎ 摘　　要

We report on our progress and development of high speed flexible graphene field effect transistors (GFETs) with high electron and hole mobilities (similar to 3000 cm(2)/Vs), and intrinsic transit frequency in the microwave GHz regime. We also describe the design and fabrication of flexible graphene based radio frequency system. This RF communication system consists of graphite patch antenna at 2.4 GHz, graphene based frequency translation block (frequency doubler and AM demodulator) and graphene speaker. The communication blocks are utilized to demonstrate graphene based amplitude modulated (AM) radio receiver operating at 2.4 GHz.
