RF module wireless transceiver rf63u chip application data transmission and infrastructure network

Application of transmitting module
　　 The launch module is DVD/DVB Audio and video wireless transmission 、 Baby monitor 、 Image monitoring of project construction site 、 Wireless camera security system 、 Imaging medical devices 、 Visual reverse camera transmission 、 Wireless video toys 、 Wireless doorbell has been widely used .
Factors affecting the launch quality of the launch module
　　1、 The antenna ： Adopt linear antenna , And parallel to each other , The remote control distance is far , But it takes up a lot of space , Lengthen the antenna in use 、 Straightening can increase the remote control distance ;
       2、 Reception sensitivity ： The receiving sensitivity of the receiver is improved , The remote control distance increases , But it is easy to be disturbed and cause malfunction or out of control ;

　　3、 Transmitting power ： High transmitting power means long distance , But it consumes a lot of electricity , Easy to disturb ;

　　4、 Height ： The higher the antenna , The farther the remote control distance is , But limited by objective conditions ;

　　5、 stop ： At present, the wireless remote controller in use is regulated by the state UHF Frequency band , Its propagation characteristics are similar to that of light , Spread in a straight line , Small diffraction , If there is a wall block between the transmitter and the receiver, the remote control distance will be greatly reduced , If it is a reinforced concrete wall , Due to the absorption of electric waves by conductors , The impact is even worse .

    RF63Uxxxx-SMT Series module is an industrial standard RF wireless transceiver integrated transparent transmission module , Working frequency 315MHz~915MHz Customizable , high stability 、 Excellent diffraction and wall penetration .

 

    The module adopts American core laboratory （Silicon Labs） Original imported SI4463 RF chip design and development , Single antenna interface （ Built in transceiver switch ）, Accurate impedance matching . The transmitting power of the module is adjustable 、 High receiving sensitivity 、 Good spectrum characteristics 、 Small harmonic 、 Small channel crosstalk 、 Strong anti-interference ability , Small size and flexible matching Placed GPIO Functional design , Make it simple 、 Easy integration into other PCB in .
