Abstract

See full text

Methods for frequency multiplying include receiving a signal having an input frequency at a frequency multiplier comprising a pair of transistors; and selecting a harmonic in the signal by connecting the transistors to a common impedance through a respective collector impedance, wherein an output frequency at the harmonic between the collector impedances and the common impedance is an even integer multiple of an input frequency.
