A feedfoward amplifier and an amplification method using the feedforward amplifier include an equalizer positioned in series with a main amplifier and/or a correction amplifier of the feedforward amplifier to compensate for a non-flat frequency response of the main amplifier and/or correction amplifier. The equalizer can be a voltage controllable equalizer adjustable under electronic controls to accommodate changing circuit conditions, or an equalizer with fixed parameters. These equalizers are selectively used according to the need and desired performance. The feedforward amplifier and the method separately perform the equalization function and the linearizing function of the feedforward amplifier to provide a cost effective and efficient feedforward amplifier and amplification method.
