PCT No. PCT/JP96/00851 Sec. 371 Date Dec. 3, 1996 Sec. 102(e) Date Dec. 3, 1996 PCT Filed Mar. 29, 1996 PCT Pub. No. WO96/31954 PCT Pub. Date Oct. 10, 1996An output power control device is provided with an isolator, to which a transmission signal, that has been power amplified by a power amplifier, is input. The transmission signal is input via a transmission line connected to an output side of the power amplifier. The isolator only passes a progressive wave component of the transmission signal. The output power control device also includes a detection circuit for forming an actual output power detection signal by extracting part of an output power from a point of input of the isolator. Further, a reactance adjusting element connected to the point of input of the isolator cancels a parasitic reactance associated with the extracting section of the detection circuit.
