With the development of 5G communication, 5G signal has been widely used in the 21st century. Like the signal system supported by mobile phones, the current 5G Mobile Phone Signal Jammer needs to interfere with all 2G \ 3G \ 4G \ 5G signals, WiFi and Bluetooth at the same time. At present, the number of jamming modules and antennas it is equipped with has been increased to at least 10-12. Taking the 5G Mobile Phone Signal Jammer of low-power type (the RF transmission power of jamming signal in each frequency band is 2-3W) as an example, the overall power consumption of a single jammer has reached 120-200w. Then the problem comes. What kind of power supply should be configured for this jammer?

A few years ago, there were usually two types of power supplies for jammers. The first type was the power adapter, which looked like the power supply of notebook computers: a closed black plastic shell. This power supply mode also belongs to the power supply of external power supply. The second type is switching power supply, which is metal hollowed out. This power supply mode usually belongs to the power supply of built-in power supply.

The current 5G Mobile Phone Signal Jammer has a power consumption of 120-200w. Because its closed structure is not conducive to heat dissipation, its maximum output power consumption generally will not exceed 150W. Coupled with the limitations of size and weight, the power adapter can no longer meet the use requirements. The switching power supply with metal shell has basically no restrictions on output power and appearance size. At the same time, it is installed inside the body of 5g mobile phone signal jammer. Therefore, at present, almost all low-power 5G jammers choose a relatively stable and reliable way of power supply by switching power supply.
