A W-band Schottky diode based frequency tripler which uses waveguide resonator filters for low loss impedance matching is presented in this paper. Impedance matching of the diodes is achieved by scaling the external quality factors and adjusting the resonant frequencies of the filter cavities. This removes most of the matching structures from the high loss microstrip circuit to the lower loss waveguide resonators. Here the output frequency of the tripler is set to be 90 GHz with a 10% bandwidth. The simulation shows a conversion loss of 13-13.8 dB in the pass-band with an input power of 13-20 dBm. The measured conversion loss over the pass-band is 13.6 -15.8 dB for 17 dBm input power and better than 14 dB at 90 GHz for 13-20 dBm input power.
