# Transmission power and power consumption of wireless signal jammer

When talking about the main technical indicators of wireless signal jammer products, key terms such as transmission power and power consumption are often involved. Then, why are the transmission power and power consumption in the wireless signal jammer easier? 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 wireless signal jammer. The transmit power here should be divided into two parts. The first is to look at the total transmit power of the device, that is, the radio frequency modules in this wireless signal jammer. Cumulative sum of power. The second is to look at the transmit power of each frequency band of the device.

Among the current mainstream wireless signal jammers, they can be roughly divided into three gears according to the transmit power of the module: the first gear is a low-power wireless signal jammer, the transmit power of each module is 2-3W, and the The transmit power is usually 30-40W. The second gear is a medium-power wireless signal 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 wireless signal 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 wireless signal jammer. In many products in the field of radio frequency, 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 wireless signal 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 is very simple, about 1/3 of the power consumption of a wireless signal jammer is converted into RF power consumption, the rest is the natural loss of power conversion, and the other part is converted into heat energy, which is why each The reason why the wireless signal jammer will be equipped with a larger size radiator.
