  • Transistor mixer and amplifier input stage
    Patent number: 4480337
    Abstract: A transistor mixer and amplifier input stage which includes a mixer and a differential amplifier whose gain is controlled by a voltage generated by an AGC circuit. Two transistors, each having a resistor connected in series with its emitter, are connected between the inputs of the differential amplifier and the mixer. When the level of the input signal increases beyond a given level, the two transistors begin to conduct, thereby shunting the differential amplifier.
