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.

A method of implementing a radio frequency (RF) switch comprises the steps of forming a first switch device on an integrated circuit substrate, forming a second switch device on the integrated circuit substrate, connecting the first switch device between a first pad and a second pad of the integrated circuit, connecting the second switch device between the second pad and a third pad of the integrated circuit, directly connecting a first control pad of the integrated circuit for receiving a first digital control signal to a control terminal of the first switch device, and directly connecting a second control pad of the integrated circuit for receiving a second digital control signal to a control terminal of the second switch device. A threshold voltage of the first and second switch devices is generally modified to allow being directly driven by the first digital control signal or the second digital control signal.
