“…Millimeter-wave and submillimeter-wave frequency multipliers [1][2][3][4][5][6] and mixers [7][8][9][10][11][12][13][14] based on planar Schottky diodes are widely used for atmosphere and space detection. The multipliers are usually driven by an oscillator [15][16][17][18] or a phase-locked millimeter-wave source.…”

Abstract-We propose a balanced frequency tripler scheme for millimeter-wave and submillimeter-wave application, in which doublesided suspended stripline is adopted. Two arms of Schottky diodes are mounted on the upper side of the substrate, and the other two arms of diodes are mounted on the lower side. The diodes are DC biased without bypass chip capacitor, which is essential in the common used balanced tripler scheme. Furthermore, the numbers of the diodes are doubled as there are only two arms of diodes in the common balanced tripler scheme, and this will double the power handling capability of the tripler. A W-band frequency tripler is designed according to the proposed scheme with commercial Schottky Varistors. The output power is from 2.9 to 5.7 dBm at the frequencies from 89.7 to 94.8 GHz, with the conversion efficiency from 1.95% ∼ 3.7%.

“…The nonlinearity of graphene has been studied extensively and verified experimentally to be widely used in many applications including harmonic generation, frequency mixers, optical rectification, amplifiers and many other nonlinear devices [18,19]. Generally, the nonlinear effect occurs when a material responds in a not linearly proportional way to the interacted incident radiation field.…”

Abstract-In this paper linear and nonlinear properties of graphene at millimeter wave frequency band are investigated. The nonlinear properties of the graphene are utilized to design frequency multiplier and mixer for millimeter wave applications. A patch of graphene is deposited on the dielectric image guide that will generate higher order harmonics. The amplitude of harmonics is optimized based on the dimensions of the graphene patch on top of the dielectric image guide. A frequency multiplier and mixer are designed, which utilize the second harmonics generated through graphene. The nonlinear behavior of the proposed designs has been simulated in the 50-75 GHz input signal frequency range. A conversion efficiency of −23 dB is obtained for the second harmonic for the frequency doubler. The frequency mixer is designed to mix two frequencies in V-band using dielectric image guide as the waveguide. A −28 dB conversion efficiency is simulated on a dielectric image-guide platform.

“…This results from the linear dispersion of the carriers in graphene, instead of the parabolic dispersion of conventional semiconductors. Some works have reported demonstration of frequency multiplier and mixer at microwave frequency range [14][15][16]. However, no systematic microwave nonlinear property study on graphene has been reported.…”

Abstract-Linear and nonlinear microwave properties of chemical vapor deposition (CVD) grown graphene are characterized by incorporating a co-planar waveguide (CPW) transmission line test structure. The intrinsic linear transport properties (S-parameters) of the graphene sample are measured and extracted via a de-embedding procedure and then fitted with an equivalent circuit model up to 10 GHz. A statistical uncertainty analysis based on multiple measurements is implemented to estimate the error of the extracted graphene linear parameters as well. Nonlinear properties (second-and third-order harmonics as a function of fundamental input power) of the sample are also measured with a fundamental input signal of 1 GHz. Clear harmonics generated from graphene are observed while no obvious fundamental power saturation is seen. The measured nonlinearity is applied in a graphene patch antenna case study to understand its influence on potential applications in terms of third-order intermodulation levels.
