  • Transistor amplifier and mixer input stage for a radio receiver
    Patent number: 4704738
    Abstract: The input stage of a radio receiver incudes a differential amplifier circuit, whose gain is adjusted by a voltage generated by an AGC circuit, and a mixer circuit. An attenuator stage with a predetermined attenuation coefficient is coupled between the input terminal of differential circuit and the input terminal of the mixer circuit. When the level of the input signal increases beyond a given value, the differential amplifier circuit is deactivated and the signal reaches the mixer circuit through the attenuator stage.
