ABSTRACT:
A signal cuber for producing the third harmonic of an input signal, for use in a signal distortion correction circuit, comprises a split-ring mixer having two ports, at which there is produced a signal at the second harmonic of the input signal, unequally terminated, whereby the second harmonic signal is reflected into the mixer to be mixed with the input signal to produce the third harmonic. The mixer can consist of transformers and diodes, which can be Schottky diodes which are forward biassed by a potential difference supplied to the ports via the unequal terminations, which may be constituted by a single resistor.
