What are the problems if the smart jammer module does not match the antenna frequency?

  • 2022/06/17

As we all know, the smart jammer consists of many interference modules with different frequencies, and these interference modules correspond to the frequencies of the antenna one-to-one, so why do they correspond to one-to-one? If not, what are the problems.

The interference module of smart jammer is divided according to the signal frequency used by mobile phone. The frequency ranges from 800M to 6G. The main mobile phone interferometers are generally divided into 10-12 interference modules. The interference 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 the interference module and the antenna of the smart jammer should correspond one to one, so that the effective frequency of the smart shield module can be fully used. In the output frequency and power covered by the interference module, the antenna corresponding to the frequency can make these signals play a greater interference role.

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

To sum up, the frequency of the signal sent by the interference module of the smart jammer should correspond to the frequency of the antenna one-to-one, so as to play the real role of the smart shield.
