A compact 128-element Schottky diode grid frequency doubler generating 0.25 W of output power at 183 GHz
Journal article, 2017

This paper presents a compact varactor grid frequency doubler encapsulated in a waveguide environment, thus providing single mode (H₁₀) waveguide connection at both input and output. Schottky diodes are used as varactors in this 128-element grid frequency doubler. By packaging the grid and its embedding network together with a stepped waveguide taper on the output, a module measuring 9 mm x 19 mm by 19 mm is created. A peak output power of 0.25 W is produced at 183 GHz with 1.32 W of input power and a corresponding conversion efficiency of 19%. The peak conversion efficiency is 23% at 183 GHz with 666 mW of input power.
