The broadband level wave-detection circuit is as shown in the figure. This circuit is the broadband amplifier that is composed of the transistor, and you can connect the rectifier diode with the negative feedback loop to form the 1OMHZ, good linearity level detection circuit. In this circuit, the VT1~VT3 use the high cut-off frequency T transistor, and these transistors can form the directly coupled type amplifier circuit; the full wave rectifier circuit is composed of the diodes VD1 and VD2; the resistances R1 and R2 have the feedback function, the A1 has the differential/single polarity conversion function.
