What is a "Mobile Signal Jammer Circuit Diagram"? The Most Authoritative Explanation.

What is a mobile jammer circuit?

A Mobile Jammer Circuit or a Cell Phone Jammer Circuit is an instrument or device that can prevent the reception of signals by Mobile Phones. Basically, a Mobile Jammer Circuit is an RF Transmitter, which broadcasts Radio Signals in the same (or similar) frequency range of the GSM Communication.

How does a cell phone signal jammer work?

The entire cell phone signal jammer circuit can be powered up using a 9V battery. The Switch S1 is used to turn ON and turn OFF the cell phone jammer. In the above circuit the 555 Timer is used as the Frequency generator. The output of the 555 timer is fed to the amplifier circuit through a 1uf electrolytic capacitor.

What are the parts of a signal jammer circuit?

For any signal jammer circuit, there are three main parts in the circuit and when combined together the output of that circuit will work as a jammer. These three main circuit parts are RF amplifier. Voltage controlled oscillator. Tuning circuit. The entire cell phone signal jammer circuit can be powered up using a 9V battery.

What are the advantages of a jammer device?

• It is efficient in blocking the transmission of signals from networks including UMTS, 3G, CDMA, GSM and PHS. • One Jammer device may not work at different frequencies, because Mobile phones operate at different frequency bands in different countries.
