Design of Microwave Triple-Frequency Multimeter Based on Multilayer MoS2
2021
In this paper, a microwave triple-frequency multiplier based on multilayer MoS2 is designed. The multilayer MoS2 stripped from the MoS2 crystal has a strong nonlinearity. It has the physical characteristics of developing a microwave multiplier, such as a tripler. A multilayer MoS2 film is used to cover the microstrip line gap, and a triple-frequency multiplier (MFT) fabricated by multilayer MoS2 is designed. If the input power of the signal source is 15 dBm and the bandwidth of the input frequency is 0.8–1.2 GHz, the minimum conversion loss through the MFT is −41.5 dBm, and the even harmonic nonlinearity is far weaker than the odd harmonic nonlinearity. Therefore, multilayer MoS2 is a promising MFT material. Finally, by adding a recycling branch behind the tripler, the third-frequency output power is increased by recovering the low-order signal harmonics.
