1km wireless transmitter and receiver module

Keywords:  rf transmitter and receiver module,  rf data transmitter and receiver module, rf ask receiver transmitter module, rf radio wireless data transmitter receiver module, rf module receiver transmitter...

The High frequency receiving module is made of import SMD device,6.5G and high-frequency triode,High Q .inductance .With the Small volume SMT decoding IC for directly using,after adding a triode and reversing amplifier driver it can be used in all kinds of anti-

theft systems and remote control systems because of its stable and reliable performance ,high sensitivity ,low power dissipation and competitive price and quality . 

Tech Specification :

Application :

Small wireless data terminal, fireproof safety system, wireless remote control system, Acquisition of biomedical signals, Meteorological and hydrological monitoring,  robot control, Wireless 232 data communication, Wireless 485/422 data communication, digital audio, digital picture, etc.

Notes:

The frequency of the DF data transmit module is 315MHZ,433mhz, it has been used the stable frequency Sound table resonator SAW, Frequency stability is extremely high.

     DF transmit module add a data transistor, the structure enable it easy to connect other fixed code circuit, rolling code circuit and Single Chip Micyoco(SCM).You don’t have to considerate the size of working voltage and output frequency signal of code circuit.

     When the voltage change you don’t have to adjust any receiver module for the DF data module has widely working voltage range 3~12V .

     DF data module has been used the ASK modem, it can reduce the power dissipation.

To avoid the influence of distributed parameter, you have better install the DF transmit module on the edge of the main board vertically, it must be away from the instruments around it about 5mm
