868Mhz ASK Modulation Superheterodyne RF Receiver Module
DL-RXS868R is an ISM band high performance superheterodyne RF receiver module. This Wireless Module adopts industrial grade RF receiving chip, which has high receiving sensitivity, and very strong anti-interference ability.
It can realize wireless signal input to digital signal output without any external circuit. The user only needs to add a simple data decoding circuit (Contains dedicated decoding chips such as PT2272 or MCU software decoding), to achieve the RF product development easily.
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.
