摘要: A non-linearity compensating circuit for a high frequency amplifier includes a first divider for dividing a high frequency input signal into two signals, a distortion generating amplifier for non-linearly amplifying the first output of the first divider, a linear amplifier for linearly amplifying the second output from the first divider, a second divider for dividing the output of the linear amplifier into first and second signals, a first combiner for combining the output of the distortion generating amplifier with the first signal to extract the distortion component of the distortion generating amplifier, and a second combiner for combining the second signal with the distortion component.
