“…With higher voltages, the increasing influence of the conduction current leads to a mixture of reactive and resistive currents and therewith to a saturation of conversion efficiency. The results of device simulations show that this occurs for conduction current densities above about 1 kA/cm 2 [32]. The measured current density and capacitance per area versus voltage characteristics according to the device structure of Fig.…”

In this project, two frequency tripler concepts for the generation of output power in the millimetre-wave range up to 230 GHz have been investigated. Both concepts make use of the advantages of symmetrical devices, whereby the first is based on a HBV (Hetero-Barrier Varactor) monolithically integrated into the rf-circuit on GaAs-substrate whereas the second one uses an ASV (Anti-serial Schottky Varactor) as nonlinear device, realised by quasi-monolithic integration on quartz-substrate. By the help of a theoretical model of both structures, design and optimisation criteria for the varactors and the tripler circuits have been deduced and verified experimentally. The results lead to an output power of 10 mW at a frequency of 210 GHz with a conversion efficiency of 13.5 % for the HBV and an output power of 15 mW at 228 GHz with a conversion efficiency of 22 % for the ASV frequency tripler.
