Wireless
RF TX module

• The form of input signal and its voltage

• The input signal is binary data with:
   

  • Data input high = 0.7 * VCC

  • Data input low = 0.0
     

• Data bit rate

• 20 to 20,000 bps
   

• power supply:

• supply voltage: 2.7 to 5.25 V        typically 3V

• supply current (transmit mode) : 26 mA-at 3 VA

• Form of output signal :

• The output signal is RF signal with:-
   

  • Power o/p = 5% dB m into 50 ohm

  • FM deviation = +1-15 KHZ

  • IF bandwidth = 65 → 85 KHZ 

  • Harmonic spurious Emissions = -50 dBc
     

• Operating temperature:-

• -20 to+70 Deg.C
   

• Optimal transmission range : 200 m
