Optimal Design of S Band with Graphene Frequency Multiplier
A graphene frequency multiplier is proposed in this paper. The nonlinear characteristics of graphene are similar to the reverse parallel diode. In order to improve the efficiency of GFM, we use the method of recovering the fundamental and fifth harmonic wave which utilizes the way of branch recovery. According to this mechanism, an S band graphene frequency multiplier is designed. During the working frequency between 500 MHz and 3 GHz, the minimum conversion loss of −20.81 dBm can be obtained at 830 MHz and the input power is 18 dBm.
