Abstract :
The paper describes the technological realisation and experimental verification of a frequency tripler for upper mm-waves. Two anti-serial Schottky diodes are used as non-linear varactor (ASV). The single GaAlAs/GaAs devices with non-uniform doping profile optimised for the desired frequency are quasi-monolithically integrated into a microstrip circuit on quartz substrate. This concept combines the advantages of the low loss properties of the applied quartz substrate with the high reproducibility of the monolithic integration. Experimental results show an output power of 15 mW at 228 GHZ corresponding to a flange to flange conversion efficiency of 22 %.
