A frequency doubler with 35 percent efficiency at W band
Abstract
Development of a high efficiency varactor frequency doubler for 100 GHz is reported. The efficiency of the doubler is greater than 32 percent at any frequency between 97 and 102 GHz and reaches 35 percent at 98 GHz. To the author's knowledge, this is the highest efficiency ever reported for a frequency multiplier above 75 GHz. The measured efficiency is in very good agreement with a theoretically predicted value. The doubler is suitable for a W-band, all-solid-state, local oscillator source.
