Multipliers for millimeterwave range sources: frequency doubler

We have developed a series of multipliers based on a planar Schottky diodes (Device 010) for primary sources radiation frequency multiplication. Multipliers are based on a ridged waveguide and/or waveguide-finline-waveguide transition. Single-mode waveguides are used for 35-178 GHz range multipliers.

Four sub-bands (GHz):
36 – 55
52 – 79
79 – 118
118 – 178
