What effect does temperature have on the frequency stability and life of mobile phone shielding devices?

1.Temperature fluctuations can affect the performance of shielding devices.

The parameters of these devices are easily affected by temperature changes. High temperatures can undermine the stability of the device. For example, when a Cell Phone Jammer operates in an area where there are signals on both sides of the interference band, it can usually work effectively. However, as the temperature increases, frequency deviations may occur. If these deviations are large, the interference frequency may deviate from its original operating frequency, resulting in reduced shielding effectiveness or inconsistent shielding effectiveness.

2.Temperature also affects the life of the device.

In general, the service life of a device decreases with increasing temperature, in an inverse square relationship. For example, let’s consider a specific device with a chip temperature of 65°C and a mean time between failures of 100,000 hours. If the temperature rises to 115°C, the mean time between failures will decrease to 30,000 hours. This shows that higher temperatures shorten the overall life of the device.
