Superheterodyne receiving module circuit using RX3310A

The RX3310A module is a receiving module specially used for ASK modulation wireless remote control and data transmission signals. The module adopts high-performance wireless remote control and data transmission special integrated circuits, including low-noise high-frequency amplifier, mixer, local oscillator, intermediate frequency amplifier, intermediate frequency filter, comparator, etc., and uses a 316.8MHz surface acoustic wave resonator, so it works stably and reliably, and is suitable for all-weather work in relatively harsh environments.
