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.
Features
● Complete monolithic UHF receiver, frequency range 450-950MHz;
● Receive sensitivity: - 108dBm
● Operating frequency: 868.35MHz;
● Transmission rate: automatically tuned at 10 kbps (FIXED);
● No need for manual adjustment, no need for external filters and inductors;
● Power supply (voltage input) range: 3.6~5.5V;
● Low power consumption: 12mA @ 868.35Mhz,
● Standby current under sleep mode is less than 0.1mA;
● Good selectivity and stray radiation suppression, easy to pass CE/FCC test;
● Good local radiation suppression, can work together with multiple receiving modules (namely “One to Many”), and will not interfere with each other when used together, no effect to the receiving distance;
● Temperature range: -40~85 C, can work even at harsh ambient temperatures.
