Abstract
A linearizer includes an input terminal, an output terminal, and a field-effect transistor having a gate connected to the input terminal, a drain connected to the output terminal and a source grounded. A supply voltage is supplied through a load circuit to the drain of the transistor. A gate voltage is supplied through a bias line to the gate of the transistor. The transistor is biased at a bias point at which a drain current of the transistor in response to the gate voltage is in an unsaturated region.
