ماژول گیرنده RXB54

ماژول گیرنده ASK با گیرندگی بالا

RXB54 superheterodyne radio receiver module, is a superior performance of the ISM band receiver module. Uers used in Taiwan brand

Industry-level RF receiver chip wireless data transmission, with high receiver sensitivity and strong anti-interference ability, without any additional


HE circuit which can be a wireless signal input to the data signal output. Users only need to plus simple data decoding circuit, namely

Can easily achieve the development of wireless products.


2. Product Features


(1) receiver sensitivity reach -108dBm;

(2) Operating frequency: 315 MHz; (special frequency can be customized according to customer requirements)

(3) Power supply voltage input range: 2.4V-5.5V;

(4) Low power consumption, 2.6MA ; data transfer rates up to 10Kbps
