1. A power amplifier comprising:
- an amplifier having an input terminal and including an amplifying transistor having a threshold voltage;
a transistor supplying a bias to the input terminal of the amplifier according to an on/off signal;
a capacitor connected between the input terminal of the amplifier and a grounding point;
a resistor connected between the input terminal of the amplifier and the grounding point, in parallel with the capacitor; and
a diode connected in series with the resistor, whereinthe diode has a threshold voltage that is lower than the threshold voltage of the amplifying transistor, andthe diode turns off after the transistor turns off.
