Friends who have some knowledge of frequency jammers know that a full-band frequency jammer will include at least ten or more signal jamming modules, and even some large jamming devices will be equipped with more than 20, Even more than thirty signal interference modules. Why is there such a large number of modules? Each of the signal interference modules is respectively aimed at a certain frequency range, and the span of the frequency range in each module generally does not exceed 200MHz or 300MHz. If the span of the frequency range is increased to 1000MHz or more, will the number of modules be reduced? Why doesn't the frequency jammer use ultra-wideband jamming signal coverage?
The reason why we limit the frequency range of each module in the frequency jammer to 200-300MHz is the result of comprehensive evaluation and trade-offs. From the perspective of pursuing the best effect, it must be that the narrower the bandwidth, the better. The signal of the same power acts on a narrower frequency bandwidth, and the final effect is definitely better than broadband coverage. However, after narrowing the bandwidth, in the face of full-band, full-standard signal coverage, it is necessary to configure a large number of jamming modules for the frequency jammer, which will quickly increase the generation cost of the frequency jammer .
From the perspective of cost control and the number of modules and antennas that reduce frequency interference, making the bandwidth of the signal interference module as wide as possible will definitely reduce the number of modules, but the frequency span is not enough. Uncontrolled expansion, because the larger the span, the lower the average output power acting on the frequency band will be, which will directly reduce the final interference effect of the frequency jammer. At the same time, due to the increase in the frequency span, it is difficult to select the matching ultra-wideband power amplifier, and it also brings a lot of challenges to the selection of the ultra-wideband antenna. All in all, with the increase of the bandwidth, its real effect is inversely proportional to the decline.
