Cell phone signal jammer7/7/2023 ![]() ![]() When the current is flowing across the inductor, it will store the magnetic energy by this voltage across the capacitor and will get decreased, at some point complete magnetic energy is stored by inductor and the charge or voltage across the capacitor will be zero. We know that inductor is used to store magnetic energy. Once the capacitor is completely charged, it will allow the charge to flow through inductor. The main function of capacitor is to store electric energy. When the circuit gets ON, the voltage is stored by the capacitor according to its capacity. ![]() The tuned circuit operation is very simple and easy to understand. The both inductor and capacitor of tuned circuit will oscillate at its resonating frequency. This oscillator or tuned circuit will produce the very high frequency with minimum damping. This tuned circuit will act as an oscillator with zero resistance. The tuned circuit consists of capacitor C1 and inductor L1. ![]() When the transistor Q1 is turned ON, the tuned circuit at the collector will get turned ON. Capacitor C6 will remove the DC and allow only the AC signal which is transmitted in the air. The amplification signal is given to the antenna through C6 capacitor. This will amplify the signal generated by the tuned circuit. So the transistor Q1, capacitors C4 & C5 and resistor R1 constitute the RF amplifier circuit. When they are combined together, the output of that circuit will work as a jammer. For any jammer circuit, remember that there are three main important circuits. If you understand the above circuit, this circuit analysis is simple and easy. So, in conclusion, I can say that this circuit blocks the signals but cannot completely jam them.Ĭircuit 2: Simple Mobile Jammer Circuit Diagram Simple Mobile Jammer Circuit Diagram Cell Phone Jammer Circuit Explanation Once I turned on the circuit, the signal bars on the phone started to reduce and finally it stopped at a single bar. Before turning on the power, my mobile phone was able to capture majority of the signals as it is displaying full bars. Capacitors – 2pF, 3.3pF, 4.7pF, 47pF, 0.1♟, 4.7♟, 47♟Īfter building this circuit on a perf board and supplying power to it, I have placed a mobile phone near the circuit (I am yet to turn on the switch).Circuit 1: Mobile Jammer Circuit using 555 In this project, I have designed two Mobile Jammer Circuits, where the first one is using a 555 Timer IC and the other one is built using active and passive components. Check your local laws before using such devices. WARNING: Blocking or Jamming Radio Signals is illegal in most countries. Basically, a Mobile Jammer Circuit is an RF Transmitter, which broadcasts Radio Signals in the same (or similar) frequency range of the GSM Communication. Circuit 2: Simple Mobile Jammer Circuit DiagramĪ Mobile Jammer Circuit or a Cell Phone Jammer Circuit is an instrument or device that can prevent the reception of signals by Mobile Phones.Circuit 1: Mobile Jammer Circuit using 555.Each jammer system is unique and best meets your price/performance requirements.
