Abstract: PURPOSE:To operate surely a protecting circuit independently of the distance to a reflection point by detecting a ratio of the power of progressive waves to that of reflected waves so that the protecting circuit for a reflected power is operated accurately even if the distance to a mismatching place is changed. CONSTITUTION:A directional coupler 17 is connected to a transmission line 12 between a power amplifier 11 and a directional coupler 13, and a part of the power of progressive waves to a load 14 is taken out from this coupler 17. The taken-out power of progressive waves is led to a detector 19 through a level adjuster 18, whose high frequency gain is changed in accordance with a control voltage, and a DC voltage V1 obtained by detection is applied to the input terminal having the negative polarity of a DC amplifier 21 of differential input type. A part of the reflected power from the load 14 is taken out by the directional coupler 13 and is converted to a corresponding DC voltage V2 by a detector 15 and is applied to the input terminal having the positive polarity of the DC amplifier 21. A DC voltage V3 of the output of the DC amplifier 21 is supplied to the level adjuster 18 as the control voltage, and the output which operates the protecting circuit is outputted from a terminal 20.
