434MHz Ask Superheterodyne Wireless Receiver RF Module

1. DESCRIPTION: 
The CY48 is a super heterodyne wireless receiving module. This module adopts the highly integrated RF wireless data transmission receiving chip, which is a high cost performance of the receiving module of ISM frequency band. It has higher receiver sensitivity, compact small size, and low price.  CY48 makes some low-end products can get rid using super-regenerative because of the limitation of price reason.  This module also improves the stability and reliability of low-end wireless products, improve the image of the product quality and enhance the product competitiveness. Any circuit that can be done without additional wireless signal input to the data signal output. Users only need to plus simple data decoding circuit, can easily achieve the development of wireless products.
