RXB18 superheterodyne wireless receiving module adopts French brand radio frequency wireless data transmission and receiving chip, which is a cost-effective ISM band receiving module. With high receiving sensitivity, small size, and low price, some low-end products can get rid of the limitation of being able to use super-regenerative modules due to price reasons, improve the stability and reliability of low-end wireless products, and improve product performance. Quality and image strengthen the competitiveness of products. The wireless signal input to the data signal output can be achieved without any additional circuits. Users need to add a simple data decoding circuit to easily realize the development of wireless products.
Product Features:
(1) The receiving sensitivity reaches -110dBm;
(2) Working frequency: 315 MHz; 433.92 MHz; (Special frequencies can be customized according to customer requirements)
(3) Power supply voltage input range: 3.6V-5.5V;
(4) Low power consumption, 5.0V @ 315MHz, 4.8mA; 5.0V @ 433.92MHz, 6.8mA Continuous data transfer rate up to 2.4K, power consumption can be lower than 50nA in power enable mode;
(5) Good selectivity and stray radiation suppression ability, easy to pass CE/Fcc international certification;
(6) Good local oscillator radiation suppression capability, multiple receiving modules can work together (that is, single transmitter and multiple receivers) and will not interfere with each other, and the use of them together will not affect the receiving distance.
(7) Temperature range: -20-70℃, it can work normally even in harsh environmental temperature;
(8) 43×7×5.00 (mm)
Application scope:
(1) Car remote control door switch (RKE);
(2) Remote control door opener;
(3) Wireless security alarm;
(4) Wireless doorbell;
(5) Wireless controller;
(6) Wireless data transmission;
Precautions:
The drive current of the data output pin of the RXB18 module is relatively weak. If the microcontroller is directly driven, the I/O port of the microcontroller must not be connected to the pull-up or pull-down resistor, and the pull-up or pull-down resistor inside the microcontroller must be set in the disabled state.
Package includes:
1 x Radio Frequency Module
