  • Adjustable reflective predistortion circuit
    Patent number: 4588958
    Abstract: A predistortion circuit of the reflective type uses antiparallel-connected diodes for the desired amplitude and phase nonlinearity. If the signal applied to the diodes is of not of the correct magnitude, the desired nonlinearity will not be obtained. The magnitude of the signal applied to the diodes is increased or decreased as required by an impedance transforming circuit. The impedance transforming circuit is tuned for the frequencies of interest. The overall distortion is reduced by applying a direct bias to the diode pair.
