Abstract
The authors report high-harmonic-content sideband generation with a Josephson junction array as center conductor of a 50- Omega coplanar line. The line was fed with a low-level microwave signal and an AC bias current with a DC offset. Over 100 harmonics of the AC signal were observed in the mixing spectrum at RF frequencies up to 20 GHz. The shape of the spectrum changed with magnetic field and DC bias point.<>
