An fm transistor is used here for making a mobile phone jammer.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 .The power supply should not exceed 3Volt

Is this circuit tested? Any recommendations for parts?
what is 100R....is it 100 ohm or somethng else?
ya its been tested. Its 100ohm

Does it work for all frequency phones like 3g and then higher frequency
@ mammukutty : Sorry this is a small circuit and only works for 2g networks

how to make 22nH inductr and what is antenna model no. ?
Thank you for taking the time to publish this information very useful! I've been looking for books of this nature for a way too long. I'm just glad that I found yours. Looking forward for your next post. Thanks :)

Where can I get the Antenna?
Sir,
i am from india and frequency used in my country by mobiles are 900 MHz and 1800 MHz. Your circuit work for 450 MHz .So in order to increase the frequency value of inductor must be varied as per my knowledge. Would you please inform me that what value of inductor i should use to reach the desired frequency, or in case if i need to alter anything in this circuit.Please inform me soon
