RXB51 Wireless RF receiver module 315MHz 433.92 MHz 

RXB51 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. RXB51 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.

FEATURES:

1,High sensitivity -110dBm.

2,Frequency: 315M/433.92MHz (custom frequency is available)

3,Low operation voltage: VCC= 3.3-5.5 V;

4,Low Current:4.8mA. 5V/315MHZ;

5, Good selectivity and stray radiation suppression, easy to pass CE/FCC international certification;

6, A good radiation suppression capability, it can work with multiple receiver modules together. (IE, single-shot and multiple-receiving) and do not interfere with each other. Using them together does not affect the receiving distance.

7,Operating Temperature:-30℃~+70℃;

8,Small Size of PCB: 29.8 x 8.5 x 5 mm;

APPLICATION:

1,Car remote control door switch (RKE);

2,Remote control door opener;

3,Wireless security alarm;

4,wireless door bell;

5,Wireless Controller;

6,Wireless data transmission
