RF Receiving Module with both ASK and FSK Modulations Available
DL-RXB3 series RF module is a universal wireless receiving module for ASK and FSK modulation, which adopts imported industrial grade radio frequency wireless data receiving chip. It has high receiving sensitivity, and very strong anti-interference ability.
It can realize wireless signal input to data signal output without any external circuit. Its superior performance makes it a good choice as RF receiving module for the automotive RKE & BCM system.Users can easily develop wireless products by simply adding a data decoding circuit.
Features
● The receiving sensitivity can reach -118dBm;
● Working frequency: 315Mhz, 433Mhz (other frequencies can be customized);
● Working voltage range: 3.6~5.5V;
● Low power consumption: 6mA;
● Power consumption can be as low as 10nA in power enabled mode;
● Common use of ASK mode and FSK mode
● Good selectivity and stray radiation suppression, easy to pass safety test;
● Good local radiation suppression, can work together with multiple modules (one to many) and will
not interfere with each other, the receiving distance also not been affected;
● Temperature range: -40~85 C (industrial grade), can work well even in harsh environment.
