Abstract: Mobile jammer circuits are electronic devices designed to disrupt or block cellular communication signals within a specified range. This abstract presents a concise overview of a mobile jammer circuit, outlining its purpose, components, and functionality. Mobile jammer circuits utilize the principles of radio frequency (RF) interference to interfere with the transmission and reception of mobile phone signals. The primary objective of these circuits is to create a localized electromagnetic disturbance, rendering nearby mobile devices unable to establish or maintain connections with cellular networks. The circuit consists of various components, including power sources, oscillators, amplifiers, and antennas. The power source provides the necessary energy to operate the jammer circuit. Oscillators generate high frequency signals that are amplified by the amplifier circuitry.
