Frequency Doubler (From 4.7 to 9.4 GHz) Using A Diode
Jeffrey Himmel · Defense Technical Information Center (DTIC) · 1994
This report discusses the design, fabrication and testing of a harmonic generator which has an input frequency of 4.7 GHz and an output frequency of 9.4 GHz. A diode was used as the nonlinear device to produce the harmonics. The designed bandwidth of the output signal was 10 percent of the output frequency, with power optimized at 9.4 GHz.
