Claim 3:
4. The high-frequency power amplifier according to claim 1, wherein the active element is a transistor having a gate terminal, and wherein
either the input matching circuit having the active element or the output matching circuit having the active element has a second resistor which has high resistance and whose one end is connected to the gate terminal of the active element and whose other end is connected to the detection circuit, and
the detection circuit has
a diode whose one end on a cathode side is connected to the coupling circuit and whose other end on an anode side is connected to the other end of the second resistor whose one end is connected to the gate terminal of the active element,
a third resistor shunt connected to the diode,
a second capacitor shunt connected to the diode, and
a second inductor shunt connected to the diode.
