| Zusammenfassung: | PROBLEM TO BE SOLVED: To effectively detect power of an output signal from a transmitter or distortion included in the signal in a power detector which detects passing power of an impedance converter arranged in a succeeding stage of a compounding point of output power of a plurality of amplifiers, for example. SOLUTION: The power detector detects the passing power of the impedance converter (a transmission line 5) arranged in the succeeding stage of the compounding point of the output power from the plurality of the amplifiers (push-pull amplifiers 1). It includes: a line (a transmission line 21) arranged in parallel of the impedance converter; and a circuit elements for the detection (a dummy load 22, or a power monitor port P3) for detection of the power coupled to the line.
