Abstract
Official abstract text for this publication.
Methods for increasing a signal frequency include generating two or more signals having a fundamental mode and one or more harmonics; phase shifting bifurcated components of the two or more signals in transmission lines; and combining the bifurcated components to create an output signal that cancels a fundamental mode, a second harmonic, and a third harmonic in the signals to produce a frequency-multiplied output signal.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for increasing a signal frequency, comprising: generating two or more signals having a fundamental mode and one or more harmonics; phase shifting bifurcated components of the two or more signals in transmission lines; and combining the bifurcated components to create an output signal that cancels a fundamental mode, a second harmonic, and a third harmonic in the signals to produce a frequency-multiplied output signal. 2. Th…
