A super-linear feedforward amplifier, for amplifying radio-frequency input signals produced in one or more frequency channels over an input band, includes a radio-frequency power amplifier, which amplifies the signals. A signal cancellation circuit loop generates an error signal responsive to distortion products in the amplified signals. A digital correction block digitally equalizes the input signals responsive to a transfer function of the amplifier, whereby the input signals are substantially canceled out of the error signal over the entire input band. An error cancellation circuit loop subtracts the error signal from the amplified signals to generate a linearized output signal.
