Abstract
In an amplification device, an amplification unit has a transistor and amplifies a signal that is input. A control unit applies, when a power source is turned on, a pinch-off voltage to a gate of the transistor before applying a drain bias voltage to a drain of the transistor and then applies a gate bias voltage to the gate of the transistor.
