Abstract
In this paper, we present the design, analysis and measurement of a 220 GHz doubler, based on a planar Schottky varactor diode. The 3D model of the varactor diodes were firstly established in a high-frequency structure simulator, then the parasitic parameters were extracted and imported into advanced design system, in order to optimize the whole circuit. The experiment on the doubler was carried out, and the measured results showed the maximum output power of 21.39 mW with a corresponding efficiency of 24% at 218 GHz, which agreed well with simulation results. The conversion efficiency exceeded 10% in the frequency range of 197–230 GHz.
