Product Description
[Receiver module ] Product Model: RX470-4
(RX470-4 is WL101-341 upgraded version, more stable performance, faster data transfer)
 
RX470-4  superheterodyne wireless receiver module is receiving UHF ASK demodulators support ASK and OOK modulation. The receiver module has high sensitivity (-108dBm),
Low-power performance, along with high dynamic range (greater than 60dB). Module uses highly integrated chip, built front-end low-noise amplifier,Mixers, filters, frequency synthesizer circuit, etc., can maximize the signal optimization.
