diodes are reported in this paper. The circuit outputs between-3.7 dBm and+ 2.0 dBm from
75 to 110 GHz. When tuned for power flatness, the output is between-4.6 dBm and-1.3 dBm
across the band. The conversion efficiency is about 1.5% in both cases. To the authors'
knowledge, this is the first reported MMIC frequency tripler to cover the entire W-band.
