Arduino GSM Jammer

Below is a simple  Arduino GSM Jammer ()
For 1800 MHz another VCO can be used.


The square wave from Arduino pin 10 fed to VCO tuning volt input which will almost cover the Required input voltage from 0.5 to 5 volts to cover the frequency range from 870 MHz to 980 Mhz
Arduino code for generating square wave 


void setup(){ }

void loop()
{
tone(10, 15000); // generate square wave
}

1).MVCO944 (870 Mhz - 980 Mhz)

2). BFG591 or SXA389  RF Transistor 4-7GHz ,1.5 Watts

1).The transistor used in this project must be working on high frequencies , any other type transistor can be used.

Power supply must be 5vdc
