Notes on the use of smart jammer

  • 2022/07/12

As we all know, smart jammers consist of many radio frequency modules of different frequencies, and the frequencies between these radio frequency modules and antenna should correspond one to one, so why should they correspond one to one, and if not one to one, what will happen?

The radio frequency module of the smart interferer is divided according to the signal frequency used by the mobile phone. Frequencies range from 800M to 6G. The mainstream interferers are generally divided into 10-12 radio frequency modules. The RF module is divided according to the frequency of the output signal, and the antenna is also divided according to the frequency of the signal.

The frequency between its RF module and antenna should correspond one to one, so that the effective working frequency of the RF module can be fully used. The output frequency and power covered by the RF module can be made to play a greater role by the antenna corresponding to the frequency.

If the frequency of the RF module does not correspond to that of the antenna, the signal of this frequency emitted by the RF module will play a very small proportion of its role. It will not play the real role of this RF module, and will also result in more spurious signals, which will affect the normal operation of other electronic devices. Secondly, it may also cause the normal transmission power of its RF module from the antenna, resulting in the self-excitation of the RF module, which causes the high-temperature burnout of the RF module amplifier of the device.

To sum up, the frequency of the radio frequency module of the smart jammer should correspond to the frequency of antenna one-to-one in order to play the true role of the jammer.
