S042P aka. SO42P. Symmetrical mixer for frequencies up to 200MHz. It can be driven by an external source or by the built-in oscillator. The input signals are supressed at the outputs. In addition to the usual mixer applications in receivers, converters, and demodulators for AM and FM, the S042P can also be used as electronic polarity switch, multiplier etc.
Ideal for making LF and VLF converters! (SAQ transmissions, DCF77, etc.)On the internet you can find many simple circuits.
