The traditional mobile phone signal blocker adopts high power broadband noise suppression technology, which has poor jamming effect and has adverse effects on the health of people in the shielded area. This paper proposes a synchronous coherent jamming technology that jams with 5G mobile phone signals. According to the characteristics of 5G base station downlink signals, the technology can conduct coherent jamming modulation to the synchronous signal in the process of mobile phone search and destroy the cell search process of mobile phone terminals. It is suitable for 5G, 4G, and other mobile phone terminals. The simulation results show that the jamming signal is coherent with the base station downlink signal, and has the advantages of narrow jamming band width and high power utilization.
