Claim 8:
9. A semiconductor device comprising:
an n-channel enhancement-mode transistor including a gate terminal and a source terminal;
an input matching circuit to which high-frequency power is input, which is connected to the gate terminal and a gate voltage supply terminal, and inside which the gate terminal and the gate voltage supply terminal are DC-connected;
a capacitor connected to the source terminal and a ground terminal, the capacitor functioning as short-circuit at a frequency of the high-frequency power;
a resistor connected in parallel with the capacitor; and
a diode having an endmost anode connected to the source terminal and an endmost cathode connected to the ground terminal, and connected in one stage or connected in series in a plurality of stages in the same direction.
