When talking about the main technical indicators of jammer products, key terms such as transmission power and power consumption are often involved. Then, why are the transmission power and power consumption in jammers more likely to be concerned? What are the key effects of it on the performance evaluation of the product?

First, let's talk about the transmit power of the jammer. The transmit power here should be divided into two parts. The first is to look at the total transmit power of the device, which is the cumulative sum of the transmit power of each radio frequency module in the jammer. . The second is to look at the transmit power of each frequency band of the device.

Among the current mainstream jammers, they can be roughly divided into three gears according to the transmit power of the module: the first gear is a low-power jammer, the transmit power of each module is 2-3W, and the transmit power of the whole machine is usually at 30-40W. The second gear is a medium-power jammer. The transmit power of each module is 10-20W, and the transmit power of the whole machine is usually 200-300W. The third gear is a high-power jammer. The transmit power of each module is 50-100W, and the transmit power of the whole machine is usually 500W-1500W. Of course, this is only a general division method, and the transmit power of the whole device is proportional to the number of built-in RF modules.

Then talk about the power consumption of the jammer. In many products in the radio frequency field, there is an approximate proportional relationship between the power emitted by the radio frequency and the power consumption of the power supply, and this ratio is usually in the range of 1:2 and 1:3. For example, if the total RF power of a jammer is 100W, then its power consumption is about 250W. At this time, some people may ask, the power consumption is obviously much more than the radio frequency power, so where does the power consumption go? It's very simple, about 1/3 of the power consumption of a jammer is converted into radio frequency power consumption, the rest is the natural loss of power conversion, and the other part is converted into heat energy, which is why each device has no power consumption. The reason why the wire signal jammer will be equipped with a larger size radiator.
