Abstract
This paper presents a new frequency doubler scheme with significant conversion gain improvement. The new design approach utilizes switching operation of FETs. All input power, in this configuration, is directed alternately to each single branch of a pair of parallelly connected FETs corresponding with the polarity of the anti-phase input signal without split of the input power, thereby resulting in enhancing conversion gain. Measurement results demonstrate improvement of 2.87 dB in conversion gain and output power relative to a single-ended structure. For doubling from 5 to 10 GHz the new scheme shows a maximum conversion gain of 11.67 dB.
