ABSTRACT:
A circuit for compensating for the nonlinearity in a high-frequency amplifier, in which a pair of a first transmission line and a second transmission line respectively have a delay line and a nonlinear distortion generating high-frequency amplifier. An input signal is divided into two signal parts, which are respectively applied to the first transmission line and the second transmission line. The vector sum of respective outputs of the first transmission line and the second transmission line is obtained to provide a nonlinear characteristic for compensating for the amplitude and phase nonlinear characteristics in the high-frequency amplifier connected in cascade to this circuit.
