High Sensitivity 433Mhz ASK RF Receiver Module 

DL-RXC808 is an ISM band high performance superheterodyne RF receiver module. This receiving module adopts industrial grade RF wireless data receiving chip imported from Europe, which has high receiving sensitivity, very strong anti-interference ability and image frequency suppression capability. It can realize wireless signal input to data signal output without any external circuit. The user only needs to add a simple data decoding circuit.

Different from the industry’s usual noise output mode, the data output port of this RF receiving module is adopts a low-level mode, which is convenient for data decoding of the back-end MCU. It can be directly applied to your wireless products or a variety of embedded applications to avoid tedious high-frequency performance debugging and effectively shorten the development cycle.

This RF receiving module uses a single chip architecture, without the need of peripheral IF filters. This RF receiving module has a digital signal output, the RF and IF tuning is automatically completed inside the chip. Therefore, the debugging process in the development is greatly saved, which can reduce your R&D cost, and enhanced competitiveness of your product.
