Abstract:
1. A Traveling-Wave Frequency Multiplier [TWFM] comprising a distributed wave oscillator providing accurate multiple phases of an oscillation; said oscillator further comprising two or more independent electrical conductors forming transmission line loops of a differential medium for traveling wave oscillations; a plurality of cross-coupled inverting amplifiers distributed along said transmission line loops; a plurality of shorted transmission line stubs to provide biasing said cross-coupled amplifiers; a plurality of resistors in series with said transmission line stubs to eliminate low-frequency mode of oscillation; a plurality of varactors to provide tuning for high frequency, high-bandwidth oscillations in the range of at least from about sub-GHz to about THz; a plurality of symmetric tapping points to tap a plurality of corresponding symmetric phases to affect higher order harmonic frequency extraction; a plurality of summing points of said symmetric phases; and a plurality of matching networks for combining said symmetric phases to affect further frequency multiplication.
