Carcinotron-driven Schottky barrier multipliers with outputs up to 600 GHz

Experimental results of harmonic generation in the submillimetric wavelength region using carcinotrons as fundamental sources are reported. The multiplier is a commercial cross-waveguide structure equipped with a Schottky barrier diode operating as a non-linear resistance. Power levels useful for many spectroscopic applications can be obtained with these wideband tunable sources.
