Superheterodyne Receiver Module with Hopping Decoder
Description of Superheterodyne Receiver Module With Hopping Decoder
RYRM02 is a ASK/OOK Super-heterodyne receiver module with learning and hopping decoder, which is used for receive on-off signal within 4 channels.
For common learning code, RYRM02 module based on the decode chips from Microchip which is paired with such as EV1527, PT2240 encode chips. This module can provides well performance in anti-jamming and stability due to adopting the heterodyne receiving schematic.
