DEVICE AND METHOD FOR MIXING ELECTROMAGNETIC WAVES WITH FREQUENCIES UP TO THE THZ RANGE

摘要

The present invention concerns a mixing device for mixing electromagnetic signals, comprising at least one mixer and coupling means for coupling electromagnetic signals to said mixer(s) so as to generate mixed signals with frequency content corresponding to sum and/or difference of frequencies of coupled electromagnetic signals. The mixer(s) comprise(s) a self-switching device (SSD) (1) with a conductive substrate and insulating features defining in said conductive substrate an elongated channel, said elongated channel providing a charge carrier flow path in said conductive substrate between first and second areas. The present invention concerns also a method for mixing electromagnetic signals.
