ABSTRACT:
An rf level sensing circuit is described incorporating a pair of oppositely poled back diodes for receiving an rf signal. The diodes are connected to the two base inputs of a differential amplifier. A voltage divider comprising three series connected resistors is connected across a voltage supply. The junction of the first two resistors is connected to one of the bases and the junction of another two of the resistors is connected to one side of one of the back diodes. The collectors of the transistors are connected to the bases of a pair of complementary transistors which in turn drive the base of an output transistor. The collector of the output transistor is connected through a conventional diode to an output terminal; a parallel network comprising a capacitor and a resistor is connected between an output terminal side diode and ground.
