We propose an arbitrary waveform generator based on Fourier synthesis from left-handed (LH) transmission lines. Cascaded varactors and shunt inductors are used to construct the LH transmission line, which can be used as an efficient harmonic generator when driven with a large signal, and as a linear phase shifter when driven with a small signal. By controlling the amplitude and phase of each harmonic, and combining them together, we can generate pulses of arbitrary waveforms.
