Superheterodyne receiving module CS906

Relevant key device information applied in this article: RX3310AT is shown in the figure, which is the schematic diagram of an amplitude shift keying (ASK) superheterodyne receiving module. The model is CS906. Its overall dimensions and external leads are exactly the same as those of CS902. The same, the center frequency is 315MHz, which can directly replace CS902, but the performance is much higher than CS902. The internal core circuit device of CS906 is a single-chip superheterodyne receiving integrated circuit RX3310AT.
