The 8V49NS0312 provides multiple output frequencies with little to no frequency mixing
which is often an issue in similar devices in the market.
The present work focuses on implementing graphene as the nonlinear element that will enable the frequency mixing operation in the millimeter wave band.
The used nonlinear frequency mixing component consists in a microstrip line with a small gap covered by a few layer graphene film exfoliated from highly oriented pyrolithic graphite.
0025 at 10 GHz) that was employed for the implementation of the graphene based frequency mixing component.
It can be observed that the efficiency in the frequency mixing operation obtained with the graphene based nonlinear component is almost frequency independent, being the variation of the output power mainly due to the frequency response of the used filters.
As a result, many non-traditional topics have been included, including the application of nonlinear optics to the synthesis of coherent radiation in regions of the spectrum where lasers fail to work well; details of a practical frequency synthesis system beyond the basics of the theory of second harmonic generation, sum frequency mixing
and parametric processes; and the frequency stabilization of lasers to cavities and cavities to lasers.
The lowpass filters at the output of the phase detectors are used both to reject the high frequency mixing
products of the phase detectors and to limit the bandwidth of the output noise.
