发明名称 Power amplifier
摘要 In a power amplifier for amplifying power using a transistor, the transistor includes a plurality of transistor units connected in parallel and having different static characteristics or pinch-off voltages. When a bias voltage applied to the plurality of transistor units is lowered, predetermined transistor units of the plurality of transistor units are turned off by pinch-off, and the remaining transistor units are in an ON state.
