Title: Cellphone Jammer Circuit Design And Implementaton
Author: Abdalhadi, Ahmed Abdulhadi Ahmed
Abstract: This research presents the design, implementation, and testing of the design. This project have implemented the First section of the device due limitations of obtaining the rest of the required components but the design and the calculations have been measured to achieve the full design. The design if manufactured correctly shall be capable of jamming the GSM 900 and GSM 1800 simultaneously and therefore jams the three well-known carriers in Sudan (Zain, Sudani, and Mtn). This project went through four phases: Phase one: studying the GSM-system to learn about signals and distortions in circuits, and how does the GSM-system filter them. Phase two: studying the Radio frequency methodology and acknowledge its participation in our project and design Phase three: collecting the parts and studying their behaviour in real-time systems Phase four: running tests and simulations The design came out as a success and we even manufactured the IF part and obtained the desired results, but failed to obtain VCO’s of the RF part for it to be manufactured as well.
