Simple Mobile Phone Jammer Circuit Diagram

                 Circuit showing a mobile phone jammer.Here i have used a fm transistor for making this circuit.Mobile phones are working in 450  MHz  frequency .Here the transmitter generate almost equal to 450 MHz  frequency there for the mobile phone does not identify the original signal but the signal range is very week so this circuit working in only 100 m range .This circuit working in only 450 Mhz .Do not give more than 3 V
