Abstract
In this paper, an 840GHz monolithic frequency tripler is designed based on a $25-\mu \mathrm{m}$ GaAs substrate and planar Schottky diode. In order to improve the conversion efficiency, an improved balance structure is used in the circuit. This structure balances the RF path while suppressing even harmonics. An electromagnetic model of planar Schottky diodes is established based on physical characteristics. The passive part of the frequency tripler is electromagnetic simulated. At a 10dBm input power, the peak conversion efficiency of the frequency tripler is 5.82%, and the maximum output power is −2.35dBm. In the frequency range of 839 GHz to 849 GHz, the conversion efficiency is typically greater than 3%.
