High Quality Superheterodyne ASK Wireless Receiving Module DL-RXR4126 


DL-RXR4126 is an ISM band high quality superheterodyne ASK wireless receiving module. This RF module uses ultra-high frequency wireless communication technology, low noise large-scale integrated circuit, has a very high cost-performance ratio, perfect anti-static protection, and high reliability. Its superior performance makes it a good choice for rolling code remote control/electric door control system and remote data transmission.

It can realize wireless signal input to data signal output without any external circuit. Users can easily develop wireless products by simply adding a data decoding circuit, which is widely used in remote control garage doors, telescopic doors, gateways, wireless curtains, etc.

It can be also used for GSM/GPS vehicle-mounted supporting systems, high reliability industrial control, communications, security and other fields. In a word, this RF receiving module is an ideal choice for system development with high requirements in complex environment.
