The key point of this approach is that no topology of the embedding network is to be chosen a priori. The optimum bias voltages and the optimum load impedances (including possible feedback circuit) are found. The method has been applied to design doublers at low frequencies from 10-20 GHz and at millimeter-wave frequencies from 20-40 GHz. Although the experimental doublers are still under measurement, first results have given good agreement with theoretical predictions %G English %L hal-00925038 %U https://unilim.hal.science/hal-00925038 %~ UNILIM %~ CNRS %~ XLIM %~ XLIM-C2S2
