れているＡＭ検波回路。[Claims for Utility Model Registration] The emitter and collector of a first transistor are connected to one and the other output terminals of a DC power supply through first and second resistors, respectively, and a cut-off bias is applied to the first transistor. A bias at or close to cut-off is supplied, an intermediate frequency signal is supplied to the base of the first transistor, a second transistor having a polarity opposite to that of the first transistor is provided, and the second transistor has a polarity opposite to that of the first transistor. a base is connected to a collector of the first transistor, and a collector of the second transistor is connected to the collector of the first transistor;
The emitter of the second transistor is connected to the other output terminal of the DC power supply, and the intermediate frequency signal is subjected to AM detection by the first transistor, and the emitter of the second transistor is connected to the other output terminal of the DC power supply. An AM detection circuit in which a detected output of the intermediate frequency signal is taken out at the collector, and this detected output is negatively fed back to the emitter of the first transistor through the second transistor.
