Generation of multi-Gigabit/s OFDM signals at W-band with a graphene FET MMIC mixer

This paper presents multi-Gigabit/s Orthogonal Frequency Division Multiplexing (OFDM) signal generation by using a graphene field effect transistor based resistive mixer at w-band. The OFDM signals consist of 64 subcarriers each carrying a quadrature-phase-shift-keying (QPSK) symbols. The results show that a bit error rate of 10 −4 is achievable for 8 Gbps data rate.
