An apparatus includes an amplifier and a bias network. The amplifier generally has a predefined linear range. The bias network is generally connected to an input of the amplifier. The bias network generally comprises a linearizer configured to provide gain expansion and extend linearity of the amplifier beyond the predefined linear range.
