433MHZ superheterodyne wireless receiver module RXB14

Product Introduction  

This RF wireless high-frequency receiving module, RXB14, has high sensitivity, up to -107dBm, ultra-small size, ASK receiving mode,

can be used for remote control, remote control, remote control vehicle, data transmission, anti-theft alarm, home appliance control, wireless toys, car anti-theft device, wireless reversing radar, remote control garage door, remote control electric rolling shutter door and window, telescopic door, remote control gate;

is an ideal choice for GSM/GPS vehicle system and industrial control, and can also be used for systems with high requirements in complex environments.

It can replace infrared receivers, has no dead angle for reception, and is easy to design and add to general remote control use.

ASK 315/433.92MHz RF Module has a receiving sensitivity of -107dBm, a wide operating voltage of 3.0V~6V, and a heart-warming price.

It has strong anti-interference ability and is particularly suitable for special industrial control places or places with harsh environments. It has a built-in automatic gain circuit (AGC). It automatically changes the front-end high-frequency amplifier (LNA) gain according to the strength of the received signal, so that the signal output will not cause phase distortion due to the strength of the signal, so it can improve the sensitivity. The receiving local oscillation is designed as a PLL image-locked loop, which has no frequency deviation and high stability. The working receiving frequency is 315/433.92MHz, and the receiving structure is a superheterodyne method. It receives OOK wireless signals and directly outputs COMS signals to the external decoding IC for decoding after receiving the signal. It is simple and convenient to use. Without any external parts, the product can be wireless immediately to increase the added value of the product.
