In this paper, we demonstrate the design, fabrication, and characterisation of the first frequency doubler circuit employing graphene diodes. Exploiting the nonlinearity reported for state-of-the-art graphene diodes, a fully integrated, balanced microwave frequency doubler is realised on a 500-μm thick quartz substrate. The presented circuit shows broadband operation from 7-13 GHz and achieves −25.3 dB of conversion gain and −15.3 dBm of output power at an output frequency of 9.2 GHz.
