Mixer circuit diagram based on LM-1496

The picture shows the basic LM-1496 mixing circuit. In the figure, the RF and carrier inputs are connected together to form a single-ended structure. The respective signals are sent from the input end through DC blocking capacitors C1 and C2. Each pin is bypassed to ground through capacitors C3 and C4. The output network consists of a 9:1 wideband RF transformer that combines the two outputs and reduces their impedance to 50Ω. The primary coil of the transformer resonates at the intermediate frequency through C5.
