Abstract
Frequency doubling in ferrites is theoretically predicted from the equation of motion of the component of magnetization that is along the dc magnetic field direction. The low conversion efficiency previously reported by the authors has been significantly improved. Efficiencies as high as -6 db have now been observed as a result of a lengthy study of geometry effects. For an input power of 32-kw peak at 9 kmc, outputs have been measured as high as 8 kw at 18 kmc. The conversion efficiency is found to depend markedly on the geometry of the ferrite.Keywords
