With the development of signal jammer for decades, there are many kinds of jammers, which have different classifications in terms of power, types of jamming signals and jamming directions. Here, we focus on an important sub category of signal jammers: conventional low-power signal jammers. With the widespread application of mobile communication terminals, that is, mobile phones, low-power signal jammers, among which the most widely used are examination rooms and prisons. The frequency band system covered by its interference signal is also gradually changing from 2G and 3G to 4G and 5G. When many manufacturers design and produce products, the basic design idea is to increase the corresponding interference frequency band (interference module) for the new mobile phone frequency band. Therefore, the whole device is composed of several interference frequency bands, which are stacked in number and installed on the radiator built in to shield the mobile phone signal. That is, when some frequency bands are added, the appearance size of the device will gradually increase accordingly. The nature of signal jammer is the combination of several jamming bands. What are the disadvantages of the previous method of continuously increasing jamming modules and equipment appearance dimensions? First of all, whenever a new generation of standard frequency band appears, customers who originally bought equipment can only buy new equipment. The old equipment can only be discarded because it does not support new frequency bands and lacks upgrade space, which causes a lot of waste!

In the face of such problems, we, Nanjing Baikang Electromechanical Technology Co., Ltd., have designed, developed and produced a new generation of modular jammers since 2022. What we advocate is that we should abandon the previous practice of unifying several interference bands into one complete machine, but instead adopt the method of pre grouping some interference bands that are used fixedly, and then assemble this grouping into a modular structure, Finally, the whole frequency jammer is assembled with only 2-3 modular structures. Advantages: When customers are faced with frequency band upgrading or technology upgrading, the original signal jammer

The modular structure of can still be retained, just add a new modular structure for assembly.
