|Frequency multiplication is a key technology that is widely used in electronic devices in a variety of areas including broadcasting and communications. Frequency doublers are straightforward; however, frequency triplers present significant challenges. A modulated output signal for a frequency tripler tends to be its fundamental frequency component.
Researchers at Purdue University have developed a graphene-based frequency tripler with an experimentally achieved spectral output purity that is greater than 70 percent, which is an improvement by a factor of 5 over current tripler technology. Graphene is an ideal material to use in this application because of its high carrier mobility. The proposed technology addresses the output power at third harmonic with current triplers where there is poor output spectral purity, while allowing for signal amplification for conversion gain in a scaled device. Equally as important, this new technology can be easily integrated into the current graphene electronic components market.
