Abstract
Disclosed is a frequency converter circuitry having square-law transfer characteristics. In order to reduce undesirable harmonic components of the output signal, the circuitry comprises a plurality of active elements, each being responsive to respective harmonic components and having a characteristic adjusting means, connected in parallel with each other so as to provide an overall input/output transfer function approximating a square-law transfer characteristic.
