Abstract :
We focus on the analysis of the optimum operating conditions for millimeter-wave varactor frequency triplers. This study is based on coupling circuit-oriented analysis with semiconductor simulation. Such an approach enables to concurrently optimize the device electrical and geometrical parameters together with achievable output power, conversion efficiency and the required loads at the specific harmonics. We employ the harmonic-balance method together with a physics-based drift-diffusion numerical device simulator
